Carousel for 10 x needle files

thingiverse

So, I had some 608ZZ skateboard bearings lying around, and decided I needed a better way of organising my set of 10 diamond needle files I use for cleaning up prints so that I could more easily pick the particular file I wanted to use. This should fit most needle files as long as the handle diameter is around 4mm (the holes in the holder are 5mm diameter). My files came with an awful rubber coating over their 3mm diameter bare metal handles, so I cut that off and replaced it with heatshrink tubing, bringing the handle diameters to just under 4mm. You will also need 2 x 608ZZ bearings, and some self adhesive rubber feet to go on the bottom of the base part to stop it sliding around on your bench. I designed this so I could hold the base between muddle-finger and thumb with one hand and spin the carousel round with the forefinger of the same hand, to select which file I want with the other hand. File holes are chamfered at the top to allow putting the file back in the hole by feel.
