Quick and easy print that integrates 11 6x3 magnets to attach the meter to any ferrous metal surface (such as your gas tank) form quick and easy idle adjustment. Mounts to the meter with 2x M3x6 button head screws. the magnets I got from amazon measured in at 5.8x2.5 so I included a modified version if that happens to you as well. The tolerance version is also for 5.8x2.5 but sizes the holes .1mm bigger if the original is too tight. The 6x3mm version has the measurements correct if the magnets were actually that size. Should be a press fit. There are holes under each magnet, these allow you to remove the magnets if you ever need to do so.

I would highly recommend gluing a thin piece of microfiber cloth to the base, this prevents scratching your paint at a very minor decrease in magnet strength. I have tested this mount and it held steady even when revving on my Honda shadow 600 VLX. https://youtu.be/2uX23FO7B1k
