I needed screw terminal posts for my bench top power supply and no place where i lived had them in stock and i didn't want to wait to get ones ordered online. So I came up with the idea of 3D printing them. I looked online and couldn't find any so I set out to design my own.
What You Need
- 3D printer (or access to one)
- #8-32 machine screw, I used 1-3/4" because thats what i had but shorter would still work
- 2 - #8-32 Hex Nuts
- Super glue
Step 1: Design and Printing
I designed everything using Solidworks because that is what i am the most fluent in.
I attached 4 .stl files, the "complete_post_terminal" is all the components placed together, I included the individual part files if anyone wants to move the parts around on there print bed.
I printed the 3 red terminals first then switched filament to black and printed the last one.
Step 2: Assembly
Refer to pictures for clarification of steps
- Press the hex nut into the top cap, super may be needed to hold the nut in depending on the accuracy of your printer.
- Place the machine screw in through the bottom piece. The ring connector is just there to show how wires can be attached on the bottom.
- The middle piece is placed on followed by another hex nut.
- Now the top can be screwed on and you are finished.
- The posts are designed to fit in a 5/8" hole
