I found my previous third hand design (https://www.thingiverse.com/thing:2442217) to be excellent for soldering, but very annoying for storage. As I regularly store my electronics gear I decided to rework it to include a complete storage case.

In addition to the new storage case, it is now designed to better match the cheap Chinese made clothes pegs commonly found in Australia.

Also, much to my surprise, the screw threads printed perfectly, even with the printer running across them horizontally. :D

The lid is not designed to slide on. Instead it drops on top about 10mm forward of the base, and then slides back to lock into the closed position.

Update: 14/11/17 Added a meshed lid to try and resolve a problem with S3D.

This is a bit weird when slicing in s3d.. doesnt show up on model just when slicing


Thats a bridge in yellow

Just added a meshed lid.

Give that a shot.

Cura works fine in the meantime. :D

Strange. Someone else also commented on their build that s3d had issues with that part, but rhino's diagnostics check it out fine. What I’ll do tonight is generate a mesh from the nurbs model and you can try that.

perfect :)
the base is printing today so lid will go up tonight

This looks perfect :)

Ill give it a go!
