3D model description

An adjustable spool unwinder.

If your extruder motor isn't on top of the machine, this is for you!

To design the model, I searched https://www.filimprimante3d.fr/ for the smallest and largest diameter coils, as well as the thinnest and widest. This model should therefore be suitable for almost all filament spools.

In addition to the 3d model, you'll need :

  • 8 ball bearings 8x19x6mm

  • 4 CHC screws M8x20 or M8x25

  • some washers to put a small gap between the bearings. (I made my own in 8x15x0.5mm) optional

  • pads or a bit of rubber to stick under the assembly to prevent it from slipping. optional

Maximum coil diameter: Ø 270 mm

Minimum coil diameter: Ø 140mm

Maximum coil width: 125 mm

Minimum coil width: 55 mm
