Tried to print jijimath's toothpaste transfer tube but it somehow did not fit as nicely as I'd like on my travel sized & regular Colgate tubes. Did some measurements and used mike_linus' Nut Job customizer to create a taller nut. this one work perfectly for Colgate tubes.Printed at 0.1 layer height and 100% infill, but you'd probably be able to get away with less. Settings used:- Component Type: Nut Nut Type: Normal Nut Diameter: 18 Nut Height: 19.5 Nut Thread Outer Diameter: 13 Nut Thread Step: 2 Nut Shape Degrees: 45 Nut Ratio: 0.5 Wing Ratio: 1 (Not Applicable)
