BCN3D+ or MendelMax double spool holder

thingiverse

I'm excited to share a modified spool holder design inspired by the original BCN3D+ single spool holder, but upgraded to accommodate two filament spools in one. This version is ideal for users with double extruders or those who prefer having two spools ready to use at any time. The upgraded holder attaches securely to a T-slot profile with a 20x20mm dimensions. If you're currently using a single spool holder, you'll need to: Print the "double_holder_set.stl" file (or print the individual files) Obtain four 608Z axial bearings Get two M8x40mm bolts Purchase two M8 butterfly nuts or standard ones However, if you're building this design from scratch for your MendelMax or a similar machine: You'll need to print the required parts Acquire eight 608Z axial bearings Procure four M8x30mm bolts Get two M8x40mm bolts Order six M8 butterfly nuts or regular ones
