I wanted to have rail system in my small workshop, for powercords and lights.
As a material i used 40 x 40 x 4mm alumine box section.
10/9/30mm bearings (inner hole/widht/outer diameter)
8mm threaded rod and M3 screws.
3D printed parts.
Step 1: Parts..
I started from box section, and cut 12mm slice out from it with circular saw.
Drilled mounting holes with countersunks.
Then i printed the parts and assembled them.
Very simple. :)
This must be one of the shortest instructables ever.. but, i think it doesn't need to be longer to show the idea.
Thanks for checking this out.
