Filament holder simple metal

thingiverse

This is my version of a filament holder with ball bearings for my PrintrBot Simple Metal. It's printed in PLA at a layer height of 0.2mm, ensuring excellent structural integrity. Inside each roller, three precision-engineered ball bearings have been carefully inserted to guarantee smooth operation and extended lifespan. Additional parts are required, including: 1 x M8 threaded rod measuring 210mm in length 6 x steel bearings, precisely engineered at 16mmx8mmx5mm dimensions 2 x M5 nuts 2 x M8 nuts 2 x wing nuts specifically designed for the M8 bolt 2 x M5 spring plungers that enhance tension and security 1 x versatile ferrule measuring 15mm in diameter with an 8mm hole precisely drilled to accommodate various configurations 1 x precision-engineered M8 washer Print Settings: Rafts: Doesn't matter Supports: Yes, to ensure the object remains stable during printing Resolution: Set at 0.2 for precise results Infill: Strategically combining 50% and 25% infill ratios, ensuring optimal structural balance between strength and material usage Notes: Print with a specific infill pattern - 50 % in the top portion, specifically engineered for the Simple Metal model, while the rest features 25% infill to achieve the perfect balance between material usage and print stability. Post-Printing: Sanding: Initially, I noticed that all holes were printed slightly undersized; a Dremel tool proved indispensable in fine-tuning the dimensions to accommodate every component perfectly. Glueing: Securely fasten the nuts - I applied a gentle adhesive solution, first bonding the 2 M5 nuts in their assigned recesses, then meticulously positioning and bonding one M8 nut within its dedicated compartment.
