Octagonal spool roller to roll them all. Easily printed in different orientations. Remixable for different attachments.

Changelog

There are multiple length variants available for different spools:

• 60mm
  Print this if you are using narrow spools that usually contain less than 1kg of filament (Fiberlogy/Prindano/Ultimaker)
• 70mm
  A common choice for a majority of 1kg spools (Creality/Elegoo/Esun/Rosa3D)
• 80mm
  For rolling thick bastards carrying a little bit more than 1kg of filament
• 90mm
  For rolling even thicker bastards
• 110mm
  For heavy 3kg spools

You can choose a specific length if you are constantly (re)using the same spool, or simply choose a longer variant if you are using filaments on spools from different manufacturers.

This spool roller has multiple attachment options:

• For 30mm threaded insert
  The most common thread on factory spool holders coming with Elegoo/Creality/Artillery/etc
• For Honeycomb Storage Wall
• For IKEA Skadis pegboard (coming soon)
• For Multiboard
• For your specific need (just remix the attached f3d)

Parts list

• 2x 608 ball bearing (in this specific application cheaper → better)

Printing recommendations

• Tune dimensional accuracy to achieve the best results
• You can experiment with printing orientation but printing vertically with an insert on top works all the time
• Use 10mm inner/outer brims to prevent corner lifting and falling
• Use manual tree supports only on 2 flat overhanging surfaces
• The roller has an embedded sacrificial layer for printing without supports
• Use material and settings that allow bridging

Assembly

1. Remove the brims and cut off a sacrificial layer from the roller using clippers
2. It MAY require some amount of post-processing(sanding) depending on how clean your supports(filament) come off
3. Slap 608 bearings on the roller
4. Attach the assembled barrel to your printer/wall/whatever
5. Drop the roller into the barrel
6. Hang your spool
7. Enjoy smooth ride
