AFFORDABLE and not like 80/20 or Item, especially the PRICE. We live 20 miles from 80/20 and it still cost us alot of money to purchase 80/20 direct from them. We had over $1000 in 80/20 for our pit organizer "general store" we call it. Most of the time we try to have Neff Engineering donate what we need.

But for parts on the robot a v-slot linear rail like this is awesome to see, especially if it will be tailored toward FRC. Here is a sample of openbuild v-slot we've been toying with.

I love some of the innovations that some other companies have been coming out with. Things like Open Beam, Maker Beam, Maker Slide, 80/20, ITEM, V-slot, etc. When we were designing these profiles we had to think carefully to optimize what FRC and FTC teams would want in their ideal profile. In keeping with this all of our designs will also be opened sourced so people can build on them and make new advances for their own specific applications.

  • Tolerance information (whether complete as if for manufacturing, or limited to that which would be useful for interfacing), including some measure of twist per distance;
  • Standard structural constants (like section moduli) for quick comparison with other systems;
  • Alloy specifications including composition and temper;
  • Finish specifications including surface treatment (composition, thickness, hardness) and bulk material properties (hardness, roughness);
  • Recommended tooling; and
  • Warranty?
Yes, we will be releasing most of the information you requested. Here is some basic info now.

Both profiles are 6063-T5 clear Type II anodized. With 2 mm flatness and 3/4 a degree twist tolerances per meter of length.

The Extrusions will be sold in single length options (to reduce shipping costs)

6ft lengths of the 1inch
1 meter lengths of the 15mm
