[question] Reasoning for M5 bolts?

[AdamuKaapan]

Hello! I've been investigating tweaking this for my own needs and printing one up. The only issue is that I also recently got myself converged onto one standard bolt size... M4 😂

Other than obviously having to adjust some sizing and placement, can you think of any issues with using M4 vs. M5 bolts in this assembly?

(Also, if there's a more up-to-date place to get information on this project or to ask questions, please let me know)
