About this 3D model
Check out my Patreon for a bit of a write-up on this design! (My Patreon supporters got this free before it was up here for sale!) This double-lidded box uses integrated cogs to open both sides together at the same time! Press the bar on one side, and the whole thing opens! There's a video on my Instagram account if you want to see it in action! More importantly, though, this all prints assembled, in-place, without supports. Just pull it off the printer and it works! I'll put a video of exactly that on Insta, too! Enjoy!
