Pencil-holder swivel
Description
This project I was inspired by <a href="http://www.thingiverse.com/thing:8433" target="_blank" rel="nofollow">http://www.thingiverse.com/thing:8433</a>. But I wanted to make an object more dynamic and closer to my needs. With some advanced Bearing 624ZZ me, so I designed this Pencil-holder swivel. To increase the weight, I created a base with a tank to be filled with sand. In addition under the base I designed two grooves for o_ring seal (section about 1.7 - 2 mm) for more friction. In reality , the sand and o_ring are optional, but all this makes the pencil-holder very stable, so you can make it run faster :) For this project you need: - 2 bearing 624ZZ - 1 4x60 screw and nut - 2-6 washers 4mm optional: - A bit of sand - O_ring (section about 1.7 - 2 mm)
