I took the great model that Yosuke built and just added a 5.1mm slot to the inside so it would be easy to install the feet with t-nuts for the 3030 extrusion.
The same settings from Yosuke I am very sure would work but I personally printed the feet out with a 0.6 nozzle and did 3 vertical shells just to add additional strength in matching Prusament Orange PLA.
I also added the 0.4 nozzle print file just in case anyone wanted it - 3 vertical shells were also used for additional strength.
The author remixed this model.
