Tái chế cuộn Prusament cho lõi refill Bambulab

Bambulab filament refills do not fit on Prusament spools because the core diameter on Prusament spools is larger (100mm > 81.5mm).
With this model, you can build a custom spool that can fits Bambulab refills from an empty Prusament spool and some screws.

Features

• Repurpose the polycarbonate parts of a Prusament spool instead of throwing them away.
• Filament-saving: can be printed from ~45g of filament, less than half of what's needed for a typical Bambulab master spool.
• Potential downside: the reassembled spool is 110mm wide (79mm if the protruding bits are cut off). Either way, it will not be AMS compatible.

Materials

• 45g of filament
• 8x M3x20 screws, doesn't matter if they are cylinder or hexagon head.
  • M3x10 work as well, but are more finicky to assemble.
• 8x M3 hex nut

Print Instructions

• enable supports for the bottom 10mm (anything above prints without supports)
• random seam position recommended
• 10% infill is sufficient
