Glorious Mag Gauges

Wanted to make some multipurpose "steam gauges" to use on a whiteboard to help drive engagement both at work and at home after reading the 4 Disciplines of Execution. So I made these up in Tinkercad. Picture is from V1 and the top of the window kept breaking so I put wedges in and added the half scale tick marks.
The back has 4 indents for 12mmx2mm round magnets, you can also use the same size for the gauge.
Have printed in PLA and ASA with no problems.
