Summary

I made a 10mm cube with 2mm struts and didnt like its thin-ness.
So I made a 15mm cube with 3mm struts.

I wanted to have something for strength testing. Obviously can also be used for calibration as well as for bridge-i-ness-ability testing.

Render engine states 1gram and about 6 min using <.5m of 1.75mm filament.
Printing at .3lh, i didnt watch time but dimensionally on my machine, came out well, maybe 1mm extra on one side at the bottom where the layers are a little more 'squashed', pillars on 2 sides appear not flush with bottom base where the 'squashing' occurrs....
