Captive Nut

thingiverse

This is a simple test piece to demonstrate how a nut can be permanently embedded in a 3D printed part. I've uploaded a STEP file of the nut trap test part so that the dimensions of the nut can be altered to meet your needs. The current test piece is designed for a M3 screw and nut. Print Settings Printer Brand: RepRap Printer: MakerFarm i3V 10 Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.25mm or less Infill: 25% Notes: To embed the captive nut you will need to use the "Pause at height" option in Cura in the "Plugins" section. This will pause the printing process so that the nut can be embedded in your part. Cura also allows you to specify the x-y position of the print head. Make sure that you move the print head so that you can access your part. If you have a movable bed style 3D printer be extremely careful that you do not move the print bed. This will cause the subsequent layers of your part to shift if the print bed is moved.
