Greetings Everyone!

Like many of you, I printed myself a Bento Box filter to keep VOCs from entering my lungs. The only thing I wasn't sure about was how to power the fans. So with that in mind, I decided to learn enough CAD to create my first 3D model from scratch (so please be kind to me :) ) to create a custom power solution that would allow me to do the following:

1. Have the PSU be external as I did not want to connect it to the internal power supply on my X1 Carbon.
2. Be able to run 2 x 40mm fans and have room for a small LED strip in the future.
3. Does NOT require any kind of modification to the printer and be easily removed if needed.
4. Have the ability to disconnect the fans or any other accessory quickly.
5. Allow me to turn the Bento Box fans On or Off using a remote, as I was not too fond of the idea of either having the fans be always on or fiddling with the power plug in the back of the printer or behind my desk to turn the fans on or off.
6. Have the ability to power an LED strip that I plan on adding to the top of my X1 for better lighting.

With the above in mind, I created the external power supply module model that you guys see. It uses a tiny little 15W Meanwell power supply to provide the 24V output and a standard C14 connector for AC input. The main version of the design allows you to have 2 x 24v outputs (15W max combined), one controlled by a remote, and the other one is always on. Both outputs are in the form of a standard JST SM 2-pin connector allowing you to power whatever small things that you might have. There is also a version with just a hole on the side allowing you to run wires as needed.

The current design is limited to a very specific list of hardware, so please review the list below to see if those items are easily available for you or not.

Required Components:

1. Meanwell RS-15-24 PSU - Link
2. Fused and Pre-wired Power Switch with IEC320 C14 socket - Link
3. Universal Wireless RF Remote Control Switch (24V) - Link
4. M3 X 5mm screws (I used M3 motherboard mounting screws that I had laying around)
5. 2 Pin JST SM Male and Female Connectors x 2 - something like this Link or you can crimp your own.
6. 4x2 Magnets x 5 - Link (used to hold the top cover to the base. Using 4x2 magnets assuming that's what most people used on their bento boxes)
7. 10x2 Magnets x 6 - Link (Used to hold the unit to the back of the printer. You can just leave it sitting in the back if you have room and don't want to get another set of magnets)
8. A method to join a couple of wires. I used a couple of Wago connectors, but you can use whatever is your preferred method.
9. Wire Ferrule's to make installation easier towards the end - Link (I only used them on the wireless switch input wires)
10. Bento Box and enough small gauge wire (22 AWG) to be able to connect the fans to the PSU.

Required Printed Components:

1. PSU base
2. PSU cover
   1. The PSU cover has the Bambu Lab logo on it that can be printed in a different color if you like.

See the Instructions document for what other parts/items you might need along with assembly instructions and other helpful files.

This is my first model built from scratch so please excuse any mistakes I might have made, and would love feedback on ways to improve the design or the included instructions. Fusion 360 file included in case certain parts are not available.
