I Wasn't finding a multiboard mount that could fit my “Jermee Isopropyl Alcohol (IPA) 99.9% Purity” that i buy on amazon and swap the cap for a spray nozzle. It rings in at approximately 88/89mm diameter so i figured i would make one. The ID of this is 91mm, so it can comfortably fit the bottle inside of it. I made a large cutout on the front section to help reduce filament usage, and it also makes attaching to multiboard much easier. This is my 2nd design, my first i was not happy with as i didn't leave much room for fingers to tighten the t-screws so this version has a large area making it much easier. You can attach this to any of the big bolts with the small bolt hole inside of it, or the pegboard holes directly on your multiboard. Just print this along with a pair of “13mm Small thread, Flat-Head, t-bolts” (https://thangs.com/designer/Keep%20Making/3d-model/13%20mm%20Small%20Thread%2C%20Flat%20Head%2C%20T-Bolt-974236) or any of the small thread bolts that work with multiboard.
