OK, first I have to say this is very thorough. All sources are there and some alternates
I have printed the whole set and a few comments.
The grommet and restrictor are so thin on the flat that I had a hard time removing them from the sheet without destroying them.
The hanger I think is too weak to hold the whole device up when screwed to the back. The base of it is coming out at .94mm thick and the curved pieces, even at 100% infill, were to weak. Might be the filament or my abilities, but on both Hatchbox PLA and ngen, they snapped with ease.
I like the design and now I am invested with all the parts bought, can you assist in any way?
