This is an integrated spool holder I designed for the Cetus3D printer by Tiertime. The holder integrates into the design of the Cetus, fitting around two of the pegs on the bottom of the printer. The printer itself acts as a counterweight for the spool holder, which allows easy access for changing out spools, and feeds nicely into the Cetus filament guide. The design also allows the power and USB cords to be easily accessible.
The spool holder is made up of just two parts: the stand itself (~6 hour print) and the screw (~3 hour print).
