Oh thats a 3DP case I made awhile ago. This specific version is currently not open sourced but there are some other variants out there from different creators that are awesome.
I have a sweep as my first split keyboard which I love, but still want to try others. What else have you used and what keeps bringing you back to the sweep?
I have 3W6 (made by weteor), KLOR, KLOTZ and TOTEM (made by GEIST) and couple more Sweeps (Choc variants). I often go back to the Sweep because as a MX spaced variant it just feels the most comfortable for me. I feel like my hands fits it perfectly: thumbs are very easy to reach and use and surprisingly the pinky feels optimal for me. When I do crave for a shorter travel distance of a switch and smaller spacing I like to go back to KLOTZ and Sweep Bling LP.
Being able to have them at various width apart is a real game changer (for me). I love to have them approximately shoulder width apart and it makes typing so much more comfortable and enjoyable. Of course it being columnar staggered instead of traditional row staggered is contributing immensely to that as well. I'd definitely suggest giving it a try. The only possible downside I could think of is when working in specific programs where you use the board one handed and need to reach for keys that are on the other side, but that can be solved by having specific keymap layers.
