Hole tester with 3D text showing intended inner diameters

thingiverse

This is a hole tester created in Rhinoceros 7 with Grasshopper that I made, whilst designing an electronics enclosure for my 3D printer, in order to test what size holes to specify such that I may sink brass inserts into it for mounting PCBs. The Grasshopper code for this uses [this 3D text generating C# code from the Rhino forum](https://discourse.mcneel.com/t/explodable-3d-text-similar-to-fabtools-3d-text-advanced/59824/4) and therefore, like all user content posted on the Rhino forum, it was made available to me [under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License](https://discourse.mcneel.com/tos#3). As such, I am licensing this work under the same license. (I've also included the ".ghcluster" file for the (really rather trivial) "PCB Standoff" component I made to tidy up my Grasshopper code, which essentially just creates two open-ended cylinders of the specified inner and outer diameters and overall height, caps them, then subtracts one from the other.)
