Adjustment/lock rings

Made myself this ring in OpenSCAD for use with the arm of this spool holder, ensuring a snug fit for the spools on there.

The OpenSCAD project was made parametric, everything from type of screw (M2, M3, M4 etc) to amount of screws (any amount supported) to inner and outer diameter of ring.

The OpenSCAD source has some dependencies on other local projects of mine thought and thus can't be uploaded easily here right now, but I can generate new alternatives for those who want it.

I've included the PETG gcode I printed with my 0.6mm nozzle and also one for the more common combination of PLA and a 0.4mm nozzle.

The model file is also included + accompanied with two example models showing the parametric nature of my OpenSCAD code:

1. A ludicrous one with same dimensions as base ring, but with ten M2 bolts rather than the three M4 bolts.
2. A big one with four M8 bolts. Outer diameter of 75mm, inner of 40mm.

The ring in the photos has been printed on my Prusa Mini+ using add:north Red Metallic PETG filament and a standard 0.6mm nozzle.
