About this model

Tool to find center of a round stock. It was inspired by the StackExchange thread "How to I drill a hole exactly in the center of a circle" where a picture of the inspiring tool is shown. The design is split into two parts so that it can be layed flat on the printbed. The split design is a sacrifice made to allow for a metric scale on the top of the part while still allow the part to be printed without overhangs. (I did tried out a "one-part" version which was oriented on the print bed in such a way that there where no overhangs). This is a major disadvantage when thinking about the square accuracy. To mitigate this issue the tolerance I incorporated is only halve of my usual tolerance in terms of recess between mating surfaces. My usual is a gap of 0.15/0.3mm. This results in 0.075mm gap …
