Improved Devo 45 RPM Adapter

Just a cleaner and slightly redsigned version of the gr0436075's original.

There is the original flat version and a version with a concave area on the bottom to accommodate some spindle designs where a solid flat bottom wont work (I have a BIC 960 turntable like this).

The spindle hole is 7.4mm in diameter so the standardized 7.26mm spindle size fits well.

I printed mine at 0.1mm layer height, 5%infill, no supports, and I turned on ironing and it looks great. Ironing is of course optional. And of course this piece should be printed in red lol.
