I wanted to be able to print from my EIBOS easdry filament dryer, and needed a rollerbearing spool holder to do it. I remixed a similar model from thingiverse, and simplified the design to make it print more quickly. This particular print is (2) assembled parts (4 printable pieces) using (4) roller bearings and m4 screws.

Materials Needed to assemble:

• (4) m4 screws 12mm length
• (4) m4 nuts
• (4) F688ZZ bearings

Assembly Notes:

The nut should be out the outside of the spoolholders, the flange can be on the inside or outside.

Print Profile Notes:

Nozzle: Suggest 0.4mm nozzle for precision fit
Wall Loops: 3 wall loops on 0.4mm nozzle, 0.6mm nozzle not recommended due to decreased layer adhesion.
Layer Height: Suggest 0.16 or 0.20mm to maximize strength (0.16mm default)
Infill: 20% gyroid
Brim: None on textured build plate. Consider brim for smooth PEI plate.
Batch Size: For optimum layer adhesion advise printing 2-4 parts at a time to keep layers hot. For large batches (4+) reduce fan cooling. PETG performs worse if layers cool too much, and you risk a layer shift on bed-slingers like A1.
Material: PETG or ABS (NO PLA, PLA is not safe for filament dryer)
Color: Any
Print Orientation: Print horizontally as seen in .3mf file.
Supports: Supports only within m4 hole, can be removed by popping out with an Allen key (from the inside)
3d Printers: Should be printable on any printer.
Filament amount required: 21.4g per 4 parts.
