Pinch Roller for Houston Instruments DMP-60 DL Plotter

cults3d

I just found a Houston Instruments DMP-60 DL plotter and on the first paper load the pinch rollers disintegrated. I designed these simple donuts to replace the stock pinch rollers and it has been working great. I'm using Solutech flexible filament. UPDATE: I added a drawing and model of a plotter pen holder by request. These should only be a starting point as I did not have time to model the threads inside the pen holder or their exact placement in the holder. The outside and most of the inside dimensions should be accurate otherwise.
