OverlapStrap Y-Roller and Chassis Drawings

Here are a few extra drawings of the parts shown in the photo from the post I did a few weeks ago.
The chassis is made from 12mm thick mdf. I chose 12mm thick mdf so that it would be the same width as the original parts that I made from 12mm thick timber, as such someone wanting to make both those parts and the chassis on a cnc router machine could make it from one sheet. I am not really sure why I chose 12mm thick for corner parts, it just seemed like a good thickness at the time.
I think its important to give as much detail as possible so that anyone else wanting to make one could do so, and so that people can make improvements. Well, I suppose that’s the whole point of open source.

As usual the drawings are here
