Spring One Way for Prusament Spool

prusaprinters

<p>I wanted a spring that was a little more robust for the Prusament Filament Spool. I have been inspired By Vincent Groenhuis and his Universal Auto-Rewind Spool Holder. I am using his rewind mechanism and am very grateful for his awesome contribution to the community. This spring is intended to turn only one direction. I have my clutches set to 14. All my clutch mechanisms are printed in PETG as well as this spring. I have included the .STL, Fusion 360 file and .3MF files for single and two color print. I'm using these and they work great for me.</p> <p>This is designed for the 'D' shaped axle.</p> <h3>Print instructions</h3><h3>Category: 3D Printer Accessories Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> i3 MK3 MMU 2</p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0.20mm</p> <p><strong>Infill:</strong> 15%</p> <p><strong>Filament:</strong> Prusament Prusament PETG PrusamentNeon Green Transparent &amp; Galaxy Black<br/> <strong>Notes:</strong></p> <p>For PRUSA i3MK3s MMU2s I verified that first layer Temp was 240 and all other layer temp was 250.
