Interior cube corner spacer - 1cm

This is used to glue 3 walls together to make a cube interior corner. It also allows for another set of 3 inner walls to be glued together 1cm inside from the first walls.
Essentially this allows for the building of concentric cubes.
I used this to make a borg cube.
The contact area with each wall if 1cm^2.

Self supporting, use 20% infil,
