Have got the 3D printer working again in a much lower capacity for now and finally finished off the chain tensioner/clip

Here is the clip on the original tensioner. Note that it is held in place by a 25mm bolt rather than the small plastic bits that often broke off:

I've also done the tensioner itself:

And here it is printed out with the spring/sprocket. I need to give this a proper test to see how it holds out. Anyone wanting to test one themselves, let me know
