FFKB case middle for 40mm Cirque

Fits the Choc wireless version of @chewiedies case and the 40mm Cirque touchpad with curved overlay. I remodeled the part in FreeCAD using the dimensions from the STL. I had to increase the height of the part a bit to fit the larger Cirque, but with my keycaps it's not too big of a difference. With lower profile caps like MBK or MCC it may look a bit strange.

On my printer in PLA, the dimensions give a strong press fit for both the magnets and the Cirque, but you may need to adjust tolerances a bit for your setup.

I might add more variations later, but you can try modifying the FreeCAD file to fit different versions of the case or different accessories. I used the weekly build but it may work in release FreeCAD or Ondsel as well.

Redesigned middle piece to fit a 40mm curved Cirque.
