Even with a chopsaw/bandsaw/mill/cnc mill/whatever, it is certainly a better real world design if you round those off to some amount. How critically important is it that you are exactly perfect? In your robot's frame, just about never.

Also, just a recommendation, While it is less pretty, using 1/32" (or preferably 1/16" or 1/8") increments instead of decimals is much less of a hassle for whoever will measure the parts, and just a couple clicks in CAD

Not trying to be a wet blanket on this design, it certainly is cool, but it would be beneficial for every party involved if you simply rounded to the most convenient dimensions, where there will be an immeasurable difference in performance, but a significant improvement in both engineering design quality, and manufacturing


*after all, the entire point of a 6 sided drive like this is for the very purpose of escaping trapping t-bones"
