50mm to 40mm threaded low profile plumbing adapter

thingiverse

I'm having a hard time fitting the floor drain with a trap into my laundry room, but I just can't seem to locate the required adapter for connecting a 50mm waste to a 40mm threaded trap. In a last-ditch effort, I whipped up one in SCAD based on the instructions you sent over - I included a copy of the model at your request, so you can see how I used the metric thread library to get it done.
