This is a replacement part for what for the lack of a better name, I will call a mop holder roller. The old one split in two and we have several of these things in our pantry and rather than buying something new and drilling new holes, I thought I would test my skill on Sketchup. I took my handy digital caliper, priceless when replicating parts, and took measurements off the broken one. I exported from Sketchup and ran the STL through Netfabb studio to make sure it was clean. Sorry about the photo quality, these are cropped from iPad photos.I printed it in ABS, no raft, one extra shell in Makerware, 10% infill. The open end is up. Part works, see the pics. I snapped it on, turned it a few times to loosen it up and hung something as a test.
