羽毛 (Umō) - A top-mount 3D-printable case for Yasui PCB by Rainkeebs. Name Umō comes from Japanese and means a "Quill" - A feather that is dipped in ink and used to write with.
This design is provided to the community completely free of charge, free of any liabilities and free to use by everyone ! Depending on your printer's calibration, you might not be able to get a good fit right away. So print at your own risk, and know your machine !
If you want to get it right the first time, it is recommended to first print out test-fit piece.stl file found in STLs/Other parts/ folder to test out
your fitment before committing to a full case print. The internal dimensions are sized exactly as the case itself, so if your PCB & plate fit right into the space inside the test piece, you should be good.
Plate STLs are included as well and they do work when 3D-printed, however you might get a better fitment & typing experience by sourcing a laser-cut POM/Acrylic plate or a FR4 1.6mm plate.
The case uses M2 heat inserts, that are melted into their mounting holes in the top piece. The plate and the bottom will then be installed into the top piece and fastened in place by M2 screws. There are a few variations for you to print, so pick out the ones that you like, it's your case !
1x Bottom (any variation)
1x Top (any variation)
1x Plate (any variation)
1x Pen holder (normal or wide, depending on your top case)
(optional) 1x Riser
(optional) 4x Rubber bumpons (max 10mm diameter for bumpon mounts in the bottom)
10x M2 heat inserts (max length ~3.5mm, longer ones might get clogged more easily)
4x 3-6mm M2 screws for plate (depends on your plate thickness)
6x 4-5mm M2 screws for bottom case
