Bigger MP Select Mini Z Axis Spacer - No Disassembly - Fusion 360

This is a Z Axis spacer for the MP Select Mini.

Every other Z Axis spacer I've tried for my printer didn't quite fit. The spacer wouldn't fit the front-to-back depth of the gantry, causing the part not to be flat, causing the z spacing to be different than advertised.

Xilvar's spacer looked really good, but I couldn't quite get the results I wanted with that openSCAD file. So, I copied the basic shape in a Fusion 360 design. Files with a pretty good range of extra z space are included, but
