Holes, holes, holes!
thingiverse
For anyone who enjoys inserting items into openings. This openSCAD-model creates a series of holes to determine the correct diameter for screws, rods, or any other object that fits through a hole. All parameters are documented within the scad-file. Nothing out of the ordinary, but I've found it useful on several occasions. The example photo displays two prints for 8 mm (7.6 .. 8.4) and 3 mm (2.6 .. 3.4). The STL file is an example for 3 mm.
