Knurled Bolt with Captive Nut
thingiverse
This is a knurled bolt with a captive nut. This is an improvement over my last model. It is already scaled with optimal thread spacing. Trying to scale it smaller will result in more difficulty breaking the nut loose. Scaling larger shouldn't be an issue. Print Settings Printer Brand: Ultimaker Printer: Ultimaker 2 Supports: Yes Resolution: 0.1mm Infill: 20% Notes: Change support settings such that they only support 90 degree overhangs. This will protect the threads from getting any support.
