After almost 2 months now of 3D printing I found the counter next to my printer became cluttered with dozens of old calibration lines and I was setting the plate on whatever I had there, old boxes or filament rolls, while I cleaned off the calibration lines. I was bending the plate on the edge of the counter, often getting the plate dirty in the process as I had to set it down to change grip to bend it in the other direction. I also found that putting the Bambu Lab scraper back in it's little holder was a two handed job and a bit awkward.

I thought if I had a little platform that was airy underneath so it would cool faster while I cleaned off the calibration lines, along with a little garbage bin for the scrap and an integrated scraper holder that you could just sort of toss the scraper into one-handed that would be handy, so I designed this. I call it the Post-Print Processing Platform, or P4 ('cause why not).

The Bambu Lab plates pop onto the tab holder easily and the air underneath allows the plate to cool fast. The little bins on each side sort of “snap” on and off for easy emptying if used for scrap. The 45 degree “Y” shape makes it easy to bend the plate in both directions if needed.

The long bridging requires supports and they were tricky to get just right. I've included a .3mf file this time along with the .step file that should include the settings I used in Bambu Studio, but in case you have to do from scratch I had the following in addition to the standard settings:

• 4 wall loops
• 15% Gyroid infill
• I used PLA Support filament for the support interface with:
  • Auto tree (hybrid) supports
  • Supports “On build plate only”
  • 10mm tree support branch diameter
  • 15mm tree support brim width
  • 15 degree pattern angle
  • 3 top interface layers
  • Rectilinear interface pattern
  • 0.1 top interface spacing
• I used no brim for the parts, just the supports
• To make the prime tower fit I had to make it 15mm in width and to avoid red bleeding into the white I upped the prime print volume to 100 mm3 although that was probably overkill.
• For the Side Bins I used Normal (auto) supports with same interface settings as above.

The filament used here is Bambu Lab Marble for both colors and PLA Support for the interface.
