Prusa i3 Spool Mount Connector

thingiverse

Connecting rod for the Original Prusa i3 MK2 filament spool holders/mount. Meant to be a press fit (printed with little to no shrinkage in PLA) on to the original Prusa arms and connect them. Part is 16mm ID, 24mm OD, and 120mm in length. Print Settings Printer: Original Prusa i3 MK2 Rafts: No Supports: No Resolution: .2 Infill: 10% Notes: Printed with a 4mm brim to aid with bed adhesion. I went with a lower in-fill percentage, but set the Slic3r to do solid in-fill every 50 layers. Printed in PLA it fit the Original Prusa arms perfectly. Post-Printing Here it is used in combination with the Prusa i3 MK1 & MK2 Spool Holder V3 - Quick Change by IsmaelPR1. It's not touching the spool, but is there to provide support in an emergency if the spool was bumped off. How I Designed This Designed two cylinders in the Windows 10 3D modeling software. One was 24mm in diameter and the other 16mm in diameter. They were both set to 120mm in height, centered upon each other, and then the smaller cylinder was subtracted from the larger.
