If my 3d printed part’s function is to move during the match, and if the initial 3d printed design of the part fits within the 3 by 5 by 2 size limit, but will be greater than that limit during the match simply because it is a movable part, is it still considered legal within the rules?

Disclaimer - this forum cannot give authoritative answers to questions related to rule interpretation - please review the [Game Manual](https://games.recf.org/achieve/2.0) or the [official Q&A](https://games.recf.org/achieve/qa) to get official answers.

That said, I found a Q&A that might answer your question, #98: [https://games.recf.org/achieve/qa/98](https://games.recf.org/achieve/qa/98) :

> If a 3D printed custom part is made up of multiple individual parts, the starting configuration of the component must be within the size volume of 3”x5”x2”. After a match begins the component could expand outside those dimensions.

Please review that Q&A (and possibly others that might be on a similar topic) and if you don’t think existing Q&As fully answers your question, please post your question in the Q&A so our Game Design Committee can give you (and other teams) some clarification.
