My first attempt at a grip for the Miyoo Mini Plus. There are two versions, the only difference is the file called "MMP Grip - Felt" is slightly oversized so you can put adhesive felt on the left and right sides for slightly cushioned fit. I personally use this adhesive felt from Amazon, which has been useful for several 3d printing projects:

The other file, simply called "MMP Grip" should be a snug fit without adding anything else.

Enjoy!
