Printrbot Pro Top Spool Roller Mount
I designed a top mounted spool holder to hold standard 1KG spools above the handle bar for the Printrbot Pro. I built up a PrintrBot Pro Adoptabot from Brook for a local robotics club and a high school (a beta unit without the TinyG Controller, ribbon cables, wiring, and other parts). To wire it I had to make a simple loom along the right hand side in place of the ribbon cable. Due to this the standard side bar mount spool holder would not have worked since the spool would have caught on the loom (also it didn't come with the bar in the donated parts). For a long time the Robotics club used one of my simple 608 bearing table rollers that are on Youmagine. But they wanted the additional desk space so I designed this roller to hold the spool above the handle bar.
The parts print without support, and there is no glue or bolts required.
As usual I have included the native Solidworks model, and then also exported X_T, STEP, Fusion360, and of course STL files. So mix, match, mod and play however you see fit.
