About this 3D model
?? DEUTSCH I sought a robust holder for my 2.5 kg material4print filament spool—but desired one adaptable to 4.5 kg and 8 kg spools as well. Happily, I had four 6200 2RS ball bearings on hand. Thus, this support-free roller holder was conceived. ✅ Features: Suitable for spools from 0.2 kg to 8 kg Designed support-free and for material efficiency Mountable with four screws on any plate Ball-bearing guided for smooth, effortless unwinding Includes STEP files for customization ? Printing Requirements: 1× Holder 2× Roller 4× Ball bearings (6200 2RS, press fit) I printed mine using PLA, 0.20 mm layer height, 20% infill. I eagerly await your variations and setups! ? New: A1 Mini compatible version added I have subtly refined the holder for seamless printing on the Bambu Lab A1 Mini , accommodating its smaller build plate. Only minor overhang reductions were implemented; functionality and stability remain unchanged. The STL file is named halter_a1mini.stl. ? Find it among the supplementary files. ? Tested with PLA, 0.20 mm layer height & 20% infill. ? If utilizing the A1 Mini version, your feedback and boosts are most welcome ? Boost Me ? Do you appreciate this model? A boost assists me in developing further practical, support-free designs! ? Liked this model? A small Boost keeps me motivated to design more tools for makers like you. Danke ? ?? ENGLISH I needed a sturdy holder for my 2.5 kg spool of material4print filament—but I wanted one that could also accommodate 4.5 kg and 8 kg spools. I happened to have four 6200 2RS bearings on hand, so I designed this support-free, heavy-duty spool stand. ✅ Features: Supports spools ranging from 0.2 kg to 8 kg Support-free design, optimized for ease of printing Mountable with four screws to any surface Bearing-guided for exceptionally smooth filament disbursement Includes STEP files for personalization ? Printing Requirements: 1× Holder 2× Roller 4× Bearings (6200 2RS, press-fit) Printed in PLA at 0.20 mm layer height, 20% infill. ? If you appreciate this model or have printed it, please consider a Boost ? ? Boost me directly (Every point fuels further creativity!) I would be delighted to see your setups—feel free to share! ? New: A1 Mini compatible version added I have made minor adjustments to the holder to ensure it prints flawlessly on the Bambu Lab A1 Mini , which has a more compact build area. Only minor dimensional reductions were necessary—functionality and structural integrity remain completely unaffected. The STL file is named halter_a1mini.stl. ? It is included in the additional files. ? Tested with PLA at 0.20 mm layer height and 20% infill. ? If you print the A1 Mini version, your feedback—or a boost—would be greatly appreciated ? Boost Me ? Do you like this model? A boost helps me develop more practical, support-free designs! ? Liked this model? A small Boost keeps me motivated to design more tools for makers like you. Danke ? ? Updates (DE | EN) ?
