So me and my team are being responsible for once and actually making a cad of our design before we build it however, we didn’t have a good way to mount our reservoir. This lead to me creating a 3d model of a mounting block. Is this legal for competition. I’m not sure if it is because it says that it is allowed to hold an official license plate. I think that it is only for a vex license plate and that I would need to find a better way to mount the reservoirs but I’m just making sure.
Welcome to the forums!
Rule R8 states that:
Non-functional 3D printed license plates, per and , are permitted. This includes any
supporting structures whose sole purpose is to hold, mount, or display an official license plate
R13 states that
Decorations are allowed. Teams may add non-functional decorations, provided that they do not
affect Robot performance in any significant way or affect the outcome of the Match. These decorations
must be in the spirit of the competition. Inspectors will have final say in what is considered “non-functional”. Unless otherwise specified below, non-functional decorations are governed by all standard
Robot rules.
The only way that a 3d printed part (I assume that that is how you were intending to make the mounting block) would be legal is if it is a nonfunctional decoration. Since license plates are nonfunctional, 3d printing those or holders for them would be legal. However, something that would hold the pneumatic reservoirs on would be functional, and a custom 3d printed one would not be legal.
One made out a vrc legal plastic, however, would be entirely legal, as long as it follows R10, would be entirely legal though:
A limited amount of custom plastic is allowed. Robots may use non-shattering plastic from
the following list; polycarbonate (Lexan), acetal monopolymer (Delrin), acetal copolymer (Acetron GP),
POM (acetal), ABS, PEEK, PET, HDPE, LDPE, Nylon (all grades), Polypropylene, FEP; as cut from a single
12” x 24” sheet up to 0.070” thick.

a. Shattering plastic, such as PMMA (also called Plexiglass, Acrylic, or Perspex), is prohibited.

Just mount it with zipties
