Fidget Caliper

I wanted to get my son into 3D printing but didn't want to risk my calipers being trashed, after making this for him I made one for myself as I didn't want to part with it, lol. On My Bambu A1 I used a 0.2mm Nozzle & Smooth Build Plate (great for adhesion on small objects) Super glue the wheel keeper in place after fitting the wheel. don't insert the ruler until the super glue is dry. Enjoy :)
