Print size tolderance test
thingiverse
I can never remember what the tolerances are for my printer when I'm designing things to fit together, so designed this little plug and hole test. Whichever one fits best will sit proudly on top of my monitor for future reference. 5mm hole and plugs of various sizes (4mm, 4.25mm, 4.50mm and 4.75mm). They all print on a small labelled base so first layer issues won't skew the measured dimensions. For reference, these measurements are for diameter. The actual accuracy is measured by one side fitting against another, aka radius. If 4mm is the best fit, then your accuracy is 0.5mm (not 1.0mm), and you should take 0.5mm off all sides of your future plugs.
