When you prototype electronic circuits, a breadboard is a good place to do this. For the circuit build, you need wire links, cut to length. It's important to keep the circuit wiring neat, to ensure that debugging is clear, so a range of wire link sizes is needed.
This links tray helps to keep pre-cut wire links in a neat and organised fashion. Here is my 3D design.
My print is made with eSUN PLA+ 1.75mm red filament, with 0.2mm layer height and 15% infill on a Bambu X1 Carbon printer. No supports required.
I hope you can find this print useful, too.
Remember to leave me some feedback or even a tip to keep me enthused to make more of these drawings.
