Spool Adapter Cap

This cap is used for adapting jantzenday’s CR-10 Spool Adapter, thing:2387254, for use with the stand-alone acrylic spool holder that comes with the Anycubic i3 Mega, and perhaps others.

The cap has an outer diameter of 30.8mm, which fits snugly, the 31 mm inner diameter of jantzenday’s spool adapter. The inner diameter hole is 16.5mm, which fits the aluminum tube of the Anycubic spool holder, or at least the one included with my printer.

A hub centered spool holder makes for a much smoother and quieter 3D printing experience. I’m using Jantzenday’s spool adapter on my CR-10 clone, so it only made sense to keep things the same for my Anycubic.

I made the outer lip of the cap small enough that the adapter nut can be threaded on to the adapter hub without removing the cap. If you’re only using jantzenday’s spool adapter for your Anycubic printer, you need only insert these caps one time.

I hope somebody finds this useful.
