Bolt and bushing set for SPOOLHOLDER by JohnSL

http://www.thingiverse.com/make:187480

You will need 4 sets of these.

My bearings had an ID of 9.5mm.

The bolt shaft is 8mm if you get 8mm bearings you may not need the bushing (maybe some washers though).

How I Designed This

I needed bolts and bushings for the bearings I already had. I used Fusion 360 and drafted them up quick. I had to make the nut a little bigger in the X and Y scale on y printer to get a good clearance, but I'm not using a high end machine.

The hex size was chosen to make use of the bed height sensor wrenches that came with my printrbot (16mm wooden wrenches).
