Reinforced Spool for Esun 1kg spools

cults3d

Spool case designed to fit with very tight tollerances, the Esun 1kg spools. The esun spools are overwound from the supplier so require a fit with less than a 1mm gap to prevent the filament from despooling off and tangling. Also, I redesigned the lovely Spannerhands design because my spools are kept inside an autoclave with the printer which has an ambient temperture of 80 degrees celsius (for warp free ABS and Nylon printing). This design works for ABS material and a very large printing nozzel (0.6mm is recomended) with a coresponding layer height to match (0.3mm recomended). Check wall thickness behaviour in the slicer to ensure no hollows for maximum stength. Also, bearing mounts are made to be glued together (once installed).
