Gauges from 1mm to 30mm both concave and convex, including the respective cases/boxes with magnets recesses.
The magnets do be used are the circular 1mm height x 5mm diameter.
This is a REMIX from https://www.printables.com/model/1055124-radius-gauge-convex-concave , done by the user https://www.printables.com/@VC_Design. I left his mark at the bottom of boxes.
The gauges are the original ones from the original model.
The author remixed this model.
The gauges holder and the lids are wider to accomodate magnets (1mm x 5mm circular magnets).
