Roller Chain support

I’ve seen pictures of people who have placed an aluminum ‘angle iron’ across the upper axis to support a roller chain.
it appears they have fabricated some kind of bracket. so before i make one on my own i was wondering if this is something that is already out on thingiverse or elsewhere. I was considering just simply tiewraping it down as a quick fix. thanks

I have been looking for this part also but haven’t found it on thingiverse? What is everyone using for the mount for the aluminum angle? Thanks

I used a piece of wood - a piece of simple molding, I think - and tie-wrapped it. Works fine, though I do hope to an aluminum angle piece eventually.
