BCN3D Sigma R16 to R20 screen frame adapter

thingiverse

So I cracked my original screen of the BCN3D Sigma R16, and bought the r20 screen in a rush, expecting that assembly would be hassle-free, but found out that it's not a plug-and-play affair. Designed with a calliper, eyeballing some measurements, and iterating the design two times I came up with this, it could use some improvement, but it does serve the function well enough now. The back insert is friction-based, but the screen frame is a bit loose and it could use some sort of adhesive/glue, I personally used reusable sticky putty (Tack-It from Fabre Castell) on both the screen frame and the back insert for extra assurance.
