Generic construction tools

By happy coincidence 8mm threaded bar fits perfectly into skateboard bearings.   This in turn enables a whole pile of simple useful prints that lets you quickly make useful gadgets quickly.

This post is work in progress for a bunch of prints that I will slowly add to that just uses the 8mm thread bar, nuts to fit and skateboard bearings.

I've used these bits for quite a few projects..will maybe get around to uploading them

Here is one quick use today, a transformer winder.  Just a few minutes printing (since I already have all this generic stuff sitting in box) and I have a much easier way to wind a transformer.   https://www.printables.com/model/161336-transformer-winder
