Various designs of LED holder, to keep LED legs and crocodile clips separated when making circuits.

The tube design makes a good insulated connection, the open base design is less fiddly, so easier for children to use.

To print:

• Flip all of the files upside down for best results.
• They are tiny, so check your bed adhesion / add a brim if needed.
• I printed in PLA, 0.2mm layer height, 15% infill - it probably doesn't matter too much what settings you use.

Files included:

• With tubes
  • 1x LED
  • 2x LED with shared ground in a row
  • 2x LED with (optional) shared ground in a column
• Open base
  • 1x LED
  • 2x LED with shared ground in a row
  • 2x LED with (optional) shared ground in a column

Improvements to be worked on at some point…

• Flip the parts, so I don't need to manually do it in the slicer.
• The +/- signs don't show up very well. I would like it to be visible at 0.2mm layer height to save on printing time as I print lots at once for educational use.
• The shared ground on the tubed column design isn't as secure as the others - the LED wires could be guided at an angle.
