A simple to use device to roll under your foot. A very good friend at work wanted to purchase one on-line but could not find any in stock. She asked if I could make her one, and I did. She likes it a lot, so I thought I would share this with others. This model was designed in Cinema4D.

Print instructions

MK3/s gCode file
If you have a Prusa MK3/s, the gCode file is ready to go in PLA. The supports are a bit tricky and are setup to make it as easy as possible to print, but a little easier to remove.

Using the amf File
If you want to use a different material you can always use the included amf file. However, I have not tested this with other materials, and the supports may become very difficult to remove with PETG.

Printing With The stl File
I have included the stl file for you to use. But keep in mind that you need to take care while setting up the supports. Most slicers, and especially PrusaSlicer, are a bit heavy handed with automatically generated supports. While you can use the automatically generated supports, you will use a lot more material and have a lot more to remove. I worked on setting up the supports to make it less difficult if you use the gCode or the amf file. Additionally, this print is on the larger side so I recommend reducing the infill to 10%.

Post Processing
Some of the "bumps" that are facing down while printing or were attached to a support will need a little smoothing. While this is not difficult with a file, you need to go slowly if it is printed in PLA to avoid over heating. If you do not do this, you will have some sharp points which will deter from its intended use!
