Internal Radius Gauges 10mm - 52mm

Here are some internal radius gauges I made.

Video with more info here https://www.youtube.com/watch?v=-mOSP9jtia4

These were made as part of a Workshop Oscilloscope Cyberdeck build - https://www.youtube.com/watch?v=-rjCJte3NZ8

These are 1mm thicker (as described in the video the ones I made were a little too thin making them difficult to handle, these are 2mm thick with a 1mm rim.

all the parts nest together and will slip on a m6 bolt (see video)

you can either download just the ones you need or download the collections which fit on a 300mm x300mm bed.
Personally I'd download individual files and print then in alternating colours to make then easier to select when measuring an internal radius.
