Adjustable 5kg Spool Holder

This is an adjustable spool holder that I designed for poly maker 5kg rolls, which will probably work on other brands as well. It is adjustable, so you can resize for 3kg and 1 kg rolls as well. The bearings are 608

Hello, I have modified the design to be more complex but in some ways more refined. It now uses a spring loaded pin to lock at pre-determined intervals instead of friction from screws. I have also rounded some of the edges as a refinement. The roller pins will lock in as I made the opening much tighter. I have also added a PTFE extension, mainly to suit setups where a PTFE line might help run filament smoothly to the desired input.  

I'm still leaving the old design as it's not as fancy, but it works for fewer materials.
