An Interlocking cube I designed to test the multi colour function of my Mendle 3

This has primarily been designed to be printed with a multi colour printer without support, but I've been getting a lot of problems with artifacts and drool from the extruders.

The feet on the base are there to improve the bed adhesion and because Slic3r doesn't have a feature to do loops for all 3 extruders to get them started, they are designed to be cut off after printing.

My first attempts at this had problems with ooze, at teh time I was using Slic3r, but have since tried Simplyfy3D and have had much better success
