FidgetRuler 100mm 608zz

thingiverse

Who says you can't have a spinner that doubles as a ruler? Well, here's a single spinner for a 608zz bearing with marks along its edge, so every time you roll it (on a table), you get a precise 10mm distance. There are larger marks for 100mm and smaller ones for 5mm each. I've also included convenient locks for the bearing. The spinner's radius is a precise 15.92mm, making its diameter approximately 100.0mm when multiplied by two and pi. This isn't a precision caliper, but it prints quickly (in just 30 minutes) and if you don't like using it as a ruler, you can always use it as a fidget or a cool bearing box. Print the locks with buildplate support to minimize sanding. A bit of sanding will still be necessary for a better touch feel, though. Come on! Relax and start measuring! It's time to unleash your inner fidgeter!
