Description

NEWS

In order to expand upon my hose adapter design, I created a generic version. This version has a base plate that can be mounted via wood screws or M3 bolts to various surfaces. This affords the ability to attach to more things, like a resin printer which I'm currently using it for. The parts work with each other, so you can use your existing parts to attach to the new base. The new design can be found at: https://makerworld.com/en/models/374008#profileId-273980.

Update 2/19/24

Some users have experienced issues with fitting the magnets in the holes. The design is meant to have the magnets press fit into the holes, so there's some expectation that they are a bit tight. Since the tolerances are a bit tight and there can be variations in the printed result, not to mention any size variances with the magnets, I've included a test print. I suggest printing out the Magnet_fit_test.stl file to test fit magnets before printing out the larger parts so you don't waste the filament. Make sure to test with the filament you plan on using for your final part. If you find that the magnets aren't fitting as expected, you can tweak your X-Y hole compensation in Bambu Studio/Orca Slicer. Make small adjustments up or down as required.

Update 1/18/24

After reviewing user feedback on the parts, I've made changes to the 3 inch and 4 inch adapters.

3 inch adapter
- Rounded the corners of the base plate and central body to improve print reliability and reduce warping with ASA/ABS
- Increased the thickness of the model where the middle section meets the base plate to increase structural integrity and improve reliability while printing with ASA/ABS
- Increased the height by 10mm to increase print reliability with overhangs by reducing the steepness of the internal angles. This matches the height of the 4 inch adapter
4 inch adapter
- Rounded the corners of the base plate and central body to improve print reliability and reduce warping with ASA/ABS
- Increased the thickness of the model where the middle section meets the base plate to increase structural integrity and improve reliability while printing with ASA/ABS
- Redesigned the placement of the magnets to fix an issue where you could only attach the hose in two directions instead of 4. This increased the amount of magnets required by 2.

** EDIT **

Per request, I added a 4 inch adapter. Due to the size of the hose, I had to make quite a bit of modifications to the model in order to be able to mount to the printer. To be able mount the base to the printer I had to add holes through the plate that holds the magnets in order to pass a wrench through to tighten the screws. To make this feasible, I had to adjust the amount of magnets and adjust the angle of the guides. Kind of ruins the symmetry that I had going, but it works.

Rear vent hose adapter for Bambu Labs X1C/P1S printers.

I designed this exhaust vent adapter so that I could attach a 3 inch hose to my X1C in order to vent outside. I wanted to have the base permanently attached to the back of the printer, while the hose could attach/detach via magnets. This gives me the flexiblity to easy remove the hose for maintenance or move to another printer/device. The 4 guides are there to provide stability and to help guide the magnets together for a strong attachment. I also wanted to be able to close off the vent hose when not in use, so I created a cover that's also attached with magnets.

In order to attach the base, I was able to utilize the 3 existing holes and the 1 available screw that are around the exhaust fan. I cut threads in the holes with an m3 tap, which is the same size as the other screws on the printer. You may be able to use small machines crews if you are unable to thread the holes yourself.

The magnets are 10x2mm cylinder neodymium magnets. I made the parts so that the magnets could be press/friction fit into the holes. The hose adapter magnet holes are a bit deeper to account for the loss of depth due to bridging. You could glue in the magnets of necessary. The magnets I sourced from Amazon weren't exactly as advertised, but measured 10x1.67mm which I designed the holes to fit.

The hose adapter diameter is a bit undersized on purpose. It's easier to fit and clamp the hose onto the smaller diameter, I hate fighting to clamp on vent hoses.

I've printed the parts using PLA, which is probably not the best choice for long term. I may reprint later on using ASA, but so far the PLA parts have held up okay. The base and hose adapter do not need supports to print. The hose cover does unfortunately need supports due to the large overhang/bridging requirements.

What does this say?

The designer has replied

@RandomKhaos

It says "Available m3 screw". That's the location of the screw that wouldn't need to be tapped and the print utilizes to mount the base.

@sam.sissom16

Printed great! Magnets were an extremely tight fit but I was able to knock them in with a hammer. Even made a small ventilation port with styrofoam for my window. Printed TPU to test and didn’t really smell any of the bad fumes. 10/10

The designer has replied

@RandomKhaos

Part of the issue with making something press fit is that the tolerances can be different between printers/filaments. Good to see that you managed to make it work for you though. I like your window setup. Really shows how the black hose is less noticeable than the shiny silver one. I found that venting outside is a much better option than relying upon the activated carbon filter that comes with the printer. I ended up removing the filter to help with the air flow.

very convenient with the magnets instead of having it fixed onto the printer.

The designer has replied

@RandomKhaos

I really wanted an easier way to detach the hose for maintenance work and this is what I came up with. Glad to see that you like the convenience too.

@Leon_ca

I printed your "Rear Vent Hose Adapter", I appreciate your work and wanted to share some feedback based on my experience. Corner Warping with ASA Material: I used ASA material for printing, which tends to have a higher shrinkage rate. I noticed significant warping at the corners. A suggestion to potentially alleviate this issue could be to redesign the corners to be rounded instead of sharp. Rounded corners might help reduce stress concentration and subsequently the warping. Fragility at the Intersection: The intersection where the circular top part meets the square bottom seems quite fragile. After examining the slicer software, I realized there are only about 4-5 layers in this wall, which might not be sufficient to withstand the considerable stresses caused by material shrinkage. This part fractured when I removed it from the heated bed. A possible solution could be to increase the number of layers or alter the design at this junction to enhance its strength. I'm attaching some images to illustrate these points. Thank you for considering this feedback, and I look forward to any future improvements you might make to the design.

Thank you for the constructive feedback! I haven't printed the parts in ASA and I was not expecting these issues, so your test is much appreciated. From what I can tell, it's not much of a problem as long as the part can be successfully printed without the warping you are seeing. Warping hasn't been an issue in my testing since the materials I've used aren't prone to warping in the first place. I took one of my test PLA prints and attempted to pull the base plate from the body, it took a significant amount of force to break. I went ahead and did my own print using ASA and I experienced similar warping issues. I then went back to my model and beefed up where the base meets the body so now it's quite a bit stronger/stiffer. I rounded the corners of not only the base plate, but also the corners of the middle extrusion. After making those adjustments I was able to print it out of ASA without issue. One other thing to note is that I almost always use a brim when printing with ASA to help reduce warping, which this model would benefit from. I'll be updating the files later tonight with the improvements. I've attached the pictures of the improved walls and corners, plus a picture of my successful print with ASA.

perfect print. excellent quality. I ordered magnets from the Amazon link and they fit perfectly and stay without glue. I printed the 4” adapter and tapped 3M holes. thanks!

@mfiumano2

I just printed the 4 inch version on my X1C and bought the magnets you linked to, and they don't fit. I checked the size of the magnets and they are 9.9mm across, but the holes on the print seem to only be anywhere btw 9.48-9.75mm. Could you respin this with holes that would fit the 10mm (at least 9.9mm) magnets?

The designer has replied

@RandomKhaos

I've double checked my model and the magnet holes are definitely 10mm x 1.67mm in size and should fit. You may need to play with your x-y hole compensation setting in Bambu Studio/Orca Slicer in order to get your holes closer to the 10mm mark. I've attached photos showing the measured hole size in Orca Slicer and caliper measurements of one of my magnets and of the printed parts holes. These were more designed to press fit into the holes, so you should expect to need to apply some pressure to insert them.

@mfiumano2

Replying to @RandomKhaos :

how did you measure the hole in bambu studio? or is that only in Orca slicer?

(Edited)

@mfiumano2

Replying to @RandomKhaos :

did you have to use that x-y comp? or does my x1c need to be calibrated somehow? could my x1c not be dimensionally accurate? Like we used to have to adjust steps on printers before? sorry to be a bother.....

@Cuesir

would it be possible to release a version with magnet mount instead of tapping the m3 holes.

The designer has replied

@RandomKhaos

While it would have been easier to just create a magnet mount without needing a base that screws in, that would have made for an unstable connection since it could slide around. I have some ideas on how I can make your request work though. I'll see if what I'm thinking is possible and let you know.

@RandomKhaos

Ok, I did manage to create a new style hose adapter that magnetically attaches to the back of the printer plate. It utilizes a base plate that guides the hose into the correct position and preventing it from sliding around. The base plate is attached with the one available screw and 3 printed clips, no need to tap the m3 holes. This design was the only way I could come up with that would let me use weaker attachment methods and is not mean to replace my original adapter. You can find the new adapter here: https://makerworld.com/en/models/179422#profileId-197347

works well. the openings for magnets are maybe a little over tight. I broke two pushing them in. I did buy the magnets recommended by the designer

The designer has replied

@RandomKhaos

Thank you for providing feedback. It does appear that some users like yourself have had some fitment issues with the magnets. Since the tolerances are rather tight, any variations can change how well the magnets press into the holes. I went ahead and uploaded an STL file called Magnet_fit_test.stl so future users can verify fitment before printing out the main parts.
