Midcase for the Viterbi keyboard by keeb.io (https://keeb.io/collections/split-keyboard-parts/products/viterbi-keyboard-pcbs-5x7-70-split-ortholinear). Provided both with wings for tenting and without. I designed these for use with the steel plates and standoffs that keeb.io provides with their kits. I'm not sure if they will work with other cases, but I don't see why they shouldn't.
I myself printed this in t-glasse to be a diffuser for underglow on a Lulzbot TAZ-5. It required a little bit of post work in order to get the provided standoffs to fit in their holes. I just used my soldering iron to heat up the standoff until it could be pushed though.
I've provided just one "hand", the model should mirrored for printing the second half.
