Double-sided version of the genius spool holder stand to accomodate 2 or more spools

thingiverse

I took the stand construction from OM3s auto-rewind spool holder design and mirrored one side to the other. This allows to put multiple spools on the same stand. I use a DIY filament dry box with a steel threaded rod and had a hard time satisfying my inner perfectionist as the spools kept unwinding themselves when the extruder had to move far and quick on the X axis. With this adaption I combined my approach with the auto-rewind function of OM3s spool holder and all problems with unwinding spools disappeared. I used PETG instead of PLA for nearly all required parts, excluding the spring. The spring was printed using PLA because this material provides mechanical advantages over PETG.
