Reworked just the Body portion of the original design as Cardboard spools (from Elegoo) needed more clearance. Those walls would grind at the cardboard and leave dust. Use the instructions and other components from "Elegoo Neptune 3/4 Pro/Plus/Max Ball Bearing Spool Holder (M6 bolt remix)” by Engineer4fun. 

M6 bolts did not fit right for me as well so would suggest “Thread adapter for the Neptune 3/4 pro/plus/max ball bearing spool holder” by luisillo for that adapter to use M5 instead.

Credit back to Rui Nelson for “Elegoo Neptune 3 Pro/Plus/Max Ball Bearing Spool Holder lowering 20mm” for the beginnings of this.

An optional SafetyCap is now included to put on the open end. This is to keep really slick or wonky spools from walking off the end.


 

Model origin

The author remixed this model.

Differences of the remix compared to the original

Removed and replaced the tray walls with triangular extrusions. Shrunk the overall height of the front by about 5mm to make getting the roll on less exacting.  Expanded the overall size of the tray just a bit so PETG prints would have clearance all around for a smooth roll of the wheel.
