For anyone doing a bathroom renovation or tub installation, you know (or soon will know) that you need to leave a 1/8" space between the flange and the framed wall. I've created a couple small parts to assist in that. The first small piece are placement spacers that hook on the top of the flange between the tub and the stud. That'll give you the correct spacing. Then, the second part is the permanent spacer that you'll install between the flange and your stud/screwing surface. I've include a flexible tab at the top for ease of placement, then cut it away once you've drilled and screwed through the flange and through the hole in the spacer. I know they're pretty simple objects, but maybe it'll save someone else having to design it if they're doing a bath install.
