25mm or 23.8mm DumbBell and BarBell TURNBUCKLE Nuts with 7mm pitch

thingiverse

It appears that solid bars possess slightly smaller threaded diameters than dumbbells. Although the difference is minute, it's significant enough to render my original turnbuckle a safety risk when utilized on larger bar weights. Consequently, I'm releasing a sturdier, bulkier turnbuckle specifically designed for solid bar bells. Please measure your effective diameter prior to printing. File: Bar_Bell_Nut Effective pitch: 7mm Rod diameter: 23.8mm Making this turnbuckle nut was quite challenging due to its non-metric and non-American standard size. File: Dumb_Bell_Nut Effective pitch: 7mm Rod diameter: 25mm or 1 inch It slides in snugly but will easily tighten. Printer settings: - PLA - .3 layer height - bridges (utilize bridges if you want these more snug than necessary) - 45% infill (the weights will crush this thing, so avoid making it weak!)
