Yet another spool holder using 608Z bearings. It consists of two pieces that can be moved independently to adapt to the spool, and can support spools of any diameter down to 150 mm.
You will need to print:
- 4 x rollers
- 2 x locks
- 1 each of left and right
As usual with Thingiverse, the .OBJ files show rotated 90 degrees clockwise around the X axis. Obviously that won't print well. Rotate the parts as needed in your slicer to print flat (Slic3r reads the files just fine, no need to rotate anything).
Assembly is pretty straightforward, you will need:
- 4 x M5x20 bolts with nuts
- 6 x M3x20 bolts with nuts (you can get away with those)
- 4 x 608Z skateboard bearings
Supports are provided in every hole. Use a screw and moderate pressure to pop each support out, or you can use pliers to break the support. (You may want to be careful with your slicer options to avoid making too strong a bond between the support and the hole).
To get the bearings in their rollers, a hammer (or rather a rubber mallet) might come in handy. Some had success with pliers. Worse comes to worst, you can print the rollers a little larger. It should be a tight fit, but not so tight that the plastic fails.
Then assemble the two pieces using the 5mm screws. The 3mm screws can be dispensed with, as desired.
Once assembled, clip each piece on the gantry by starting from the top rear, and clipping in the front.
This model is compatible with my new filament guide.

Supports are provided in the model files.
Pop the supports with a screw.
