Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3738886.

I designed this because I did not found any model based on the original, to replace a lost rubber foot of my 3DR Iris+.

Have not tried printing it with TPU (which seems to be the perfect material for this), only ABS.

The print pictured above fit almost perfectly tight, using Simplify3D as the slicer. I recommend printing with low speed values if your slicer does not decrease your printer's speed according to the size of the model.
