Openbuilds Mini V Gantry Shim for K40 Laser Cutter - 21.2mm

This shim is used as part of my Openbuilds-based rail system re-design for the K40 "Cheap Chinese" Blue and White 40W Laser Cutter (commonly bought off eBay). It's a remix of the Openbuilds Mini V Gantry itself, to ensure a uniform fit.

The shim is necessary to ensure the height of the various mirror stages remains accurate and consistent.

You can see the application of this shim in context by reviewing the build itself on Sketchup Warehouse here: https://3dwarehouse.sketchup.com/model/074
