Built to fit my IFKB Sofle RGB. I used the template from the github sofle case svg (https://github.com/josefadamcik/SofleKeyboard/blob/master/Sofle_RGB/Case/Sofle_RGB.svg) so it should fit most.
The author remixed this model.
I was inspired by this model but it didn't quite fit right with the way the IFKB PCB is laid out and I didn't want as much height. I modelled this from scratch but I went with the same basic design.
