Replacement diffuser for japanese ODELIC wall light

I knocked mine off the wall. It broke. This is a direct replacement for the ODELIC light. There is a SCAD file and an STL file. Print using 0.3 layer height using white filament. Afterwards, I would use only LED bulbs in the fixture - I am sure the PLA would melt under a 60 watt.

Model number is either:
KR60W
0B080488
or
ML1036
