There are two versions: one that goes from 4 to 36mm in 2mm steps and one that does that only to 20mm and from there on in 5mm steps - because most metric screws are available in 5mm steps above 20mm.
It has a M5 printed thread where you can insert a screw so you have a grip to pull it out when surrounded by larger boxes.
This is not a simple “Throw two prints together” thing, was some hours of work. Leave me a make if you like it, Thank you!
Ps: better print with a 0.4 Nozzle, my try with the 0.6 did not look that well.
Pps: Print two while you are on it. If you are like me, you may loose one from time to time. The extra one is also a great gift for workshop visitors :)
