This design was inspired by the SlantSpool by Slant3D and MasterSpool by Richard Horne


While I was looking for MasterSpool compatible filaments I found the wonderful simplistic SlantSpool design by Slant3D:
This spool prints super easy, faster than the original MasterSpool by richrap (https://www.thingiverse.com/thing:2769823 or https://www.youmagine.com/designs/masterspool-for-3d-printing-filament-v4) and uses less raw filament. There’s only one part in the design you have to print twice. The two halfs of the spool connect with a simple latching system. Unfortunately the SlantSpool is designed for 1 kg refill coils so the 850 g refill coils available in Europe don’t work well on it.

The CarbonoidSpool is a hybrid of MasterSpool and SlantSpool. It uses the same latching system like the SlantSpool (which I had to clone in Fusion360 because only the STL files are available). Every spool half has 6 filament attachment points for a total of 12! per CarbonoidSpool. It works with 1.75 and 3 mm filament. There’s also a place for the sticker that comes with the filament refills to label the spool properly.
CarbonoidSpool is designed for 850 g refill coils. I also made a bigger version for 1 kg refill coils.

The 3D models, STL and more fotos are also available from my GitHub repo:

Materials and methods

I printed the two halfs of the CarbonoidSpool with PLA on of my Carbonoid D1 Delta 3D printers with 100 mm/s maximum print speed and 200 mm/s travel speed.

Filament: PLA (recommended)
Layers: 0.3 mm
Perimeter shells: 3
Infill: 15% grid infill

Carbonoid Spool 850 material usage @ 0.3mm, 15% infill
One half
Build time: 4 hours 11 minutes
Plastic weight: 115 g (0.25 lb)

Build time: 8 hours 22 minutes
Plastic weight: 230 g (0.50 lb)
