This design is for a Prusa MK4 was inspired by user MSB on Printables who made a design for the MK3.
Why did I design this?
I wasted 2 days trouble shooting bad prints only to discover I had a 0.6 nozzle installed but I had hardware and software set to 0.4 mm. Work interruptions can cause these problems. I thought a reminder is needed and I found a very nice design by MSB. After I printed it, I realized it doesn't fit an MK4 so I redesigned the case and wheel for my printer. The MSB wheel will also fit my case. His has leading zeros and mine has a closer fit on the bearing.
Printing
I used PETG and recommend leaving the fan off for the case part to possibly increase strength of the attachment features. PLA may work but I did not test it. The wheel is designed for one .2 mm layer of contrasting color which can be printed on on the build sheet or facing up. A very opaque color should be used for that single layer because many colors are somewhat transparent. The wheel can be printed with 2 perimeters and 15% infill. The case should be printed with 5 perimeters and 15% infill. To install, hang on the frame by the top two legs and snap the bottom on as it has a chamfer for engagement of the frame. When
