Paint Roller Filament Holder for M3D printer

Yannicflight's M3D spool holder, based on a paint roller handle, is brilliant. Unfortunately, it didn't fit my M3D printer, for reasons unknown. This is a modification for a part that does fit mine. Also included is a FreeCAD model, so you can tweak it as needed.

Update: by request, there's now a version with a 10mm (actually 10.2mm for clearance) hole. There's also a FreeCAD model for the new version.
