3D printed rim Joiner

 

Setup of joiner for cube - see line 2 of diagram below

Cube (table without tabletop) with one side missing. This is sturdy enough but it rocks a bit. Any bigger and it wouldn't fit through the door!

I thought this would be ok but it was a bit flimsy

Tetrahedron with now very rusty steel joiners

New joiners with internal washer spacers set up for cubes.

After making the icosahedron sculpture and having difficulty making the joiners without sharp edges, I decided to have a go at something else, and came up with a design for a 3d printed part that would do the same thing. It could have lots of advantages compared to the processed steel parts I had been making and using:

* Able to make one part that's versatile for different platonic solids and prisms without extra effort

* Should be rustproof.

* Made from strong PLA+ material

* No need for deburring as 3d printing with a 0.6 nozzle

However on the other side, 

* May not be as strong as steel, so care needs to be taken with assembly.

 So I've started on a cube, I aim to build the icosahedron cubby house next, wish me luck!
