This is a remix of the mounting bracket of the “Filler Spool Holder” for the Anycubic Chiron. I have these on my Anycubic Mega (I did that remix too)and both my Ender 3’s. Reduces drag on filament feeding, especially on the Chiron with that textured squarish folded metal, that doesn’t make much sense. It only adds 39 g of weight. I did many versions until I liked the balance of the function and aesthetics.

I printed the yellow holder and black bracket with generic PLA. The actual roller is eSun PETG printed at a .32 layer height on my Anycubic Mega for added strength and to save print time.

The "Filler Spool" holder files used with the mounting bracket are:

3DPNFilHoldRoller

I printed the adapter inverted. It uses less support material, easier to clean up and gives a better visual appearance with the Ultrabase finish.

You will need "608ZZ 8x22x7 Shielded Greased Miniature Ball Bearings" Link:

This remix uses the original bracket that attaches to the Chiron. Remove the holder's two M3s. You will need 2 "M3 12mm & nuts to attached the new adapter. I used small needle nose pliers to help assembly. There is plenty of clearance, for the M3 nuts, due to how the metal is folded.

I hope you enjoy this simple and useful mod.
