An improved 3D printer filament spool holder / roller for my Makergear M2 3D printer.
The holder / roller is designed to fit a standard Makergear filament spool.
This is just another excuse to give my lathe a bit of a workout :)
The original filament spool holder on my Makergear M2 although functional, leaves much room for improvements.

How It’s Made
Check out the video above for the build, took half a day from start to finish. Mostly involved turning (aluminum and delrin) down to size, and tapping a few screw threads.
I could as well print the plastic roller on my printer, but no 3D printer (the affordable ones at least) can beat the smooth and precise finish a lathe can achieve.
And the choice of aluminum is of course due to it being much stronger than plastics (ABS or PLA). I’m using 6061 Aluminum, it is easier to work with, and produces better finish when turned on a lathe.
Bits And Pieces
The existing mounting holes on the frame allows for direct mounting of the new holder / roller.

The aluminum shaft and the mounting plate attached directly to the frame.
The delrin roller, outside diameter turned to fit the standard Makergear filament spool, and the inside diameter was bored to fit the shaft and bearings.
