Hi,
I remixed the Phone Case for the cmf 1 by Nothing by Edward Patel here: https://www.printables.com/model/986566-cmf-phone-1-case-for-tpu-with-freecad-file
This is a complete redraw of the original in FreeCAD with:
rounding holes
thicker bottom
hole for top mic?
button cover changed to slots
covered charging port (you can slicer the cover of in 3 side)
additional small clamp at the corners for more stable grip on phone
Happy printing!
