mutliboard 6x6 spikes on different sides

This is a remix of the 6x6 mutliboard with having spikes on opposite sides of each other. When I was printing this I was annoyed that some of the pieces had gaps inbetween them because I printed 1 extra core. So I made this so that the gaps are gone.

Based on the works of Jonathan Kobylanski AKA "Keep Making" on
