Summary

Slight variation on design, cuts down on material but is more than strong enough. I printed this in ABS and Nylon and both were wayyy stronger than needed. If printed in the default orientation of the STL, obv will be the strongest but will need supports. Can print with the base side down and can print successfully with no supports. Also got rid of the connector thing in the middle, it just seems like a bit of a waste of material. However I was thinking about making a mat that is intended to be printed in TPU and fit securely between 2 of these. Will upload if I do or anyone would have interest. Model files included as well.
