Mop Handle to Acme Broom Handle Adapter UPDATED 8/11/2024

by ElTorro5150

*UPDATE* I have updated my model with reinforcement where the threads meet the adapter. The threads kept snapping off if the broom head hit an object at an angle. Print the threads all the way down to the base of the oval at 90 to 100% infill. This latest design was printed with ASA filament, but any filament should be fine. This is a remix, thank you to the original designer because I could not figure out how to design Acme threads in Fusion 360. The original design is by XDGun and can be found here.I needed a new handle for my shop broom. I had an old mop handle that used a spring clamp design to hold a disposable cotton mop head. After removing the clamp I had a nice, long handle with two holes ready to accept an adapter. The through bolts are M6x50mm but 45mm bolts might work.I printed the threads at 100% infill for strength and the rest of the body at 25%. Sliced using PrusaSlicer and printed out of HT-PLA+. So far it has held up fine. I have included my config file for PrusaSlicer. Print the big end on the build plate, you should not need any supports.Print SettingsPrinter Brand:CrealityPrinter: Ender-3 MaxRafts:NoSupports: NoResolution:.6 nozzle 20mm NORMAL speedInfill: See summaryFilament: Filacube HT-PLA+ Machine Gray Category: Hand Tools
