About this 3D model

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.
