Remixed wall mount spool holder originally by MasterD. Loved his simple design but wanted something stronger.
Fortified / combined with a simple triangle-shaped bracket found on thingiverse.
Upgraded physics result in improved resilience to mechanical and gravitational pull. Printed with PLA. Can easily handle 1kg spools.
IMPORTANT: Print at 30% infill at least & increase outer wall to ca. 1.5mm or 2mm or use 4 shells so it can handle a spool's weight
Use strong / thick screws or nails for wall mounting and a filament guide or filament filter + filament guide tube or a few filament guides / rings to create a gentle curve :)
The relict 'holes' on the small triangle bracket actually enhance object's stability.
0.14mm but 0.3 can work too
IMPORTANT: Print at 30% infill at least & increase outer wall to ca. 1.5mm or 2mm or use 4 shells so it can handle a spool's weight.
Use a filament guide tube and an additional filament guide. Maybe add a filament filter as well.
Used a simple cable holder as guide, a universal filament filter and elastic guide tube
