I present to you all, my latest creation... ZYNtastic. Available on Printables here: https://www.printables.com/model/1043785-zyntastic-case-for-the-haltec-v3
Inspired by my friend Z3R0, this case for the Haltec v3 meshtastic board fits inside of a ZYN can. With just enough room for the included antenna and a 750mAh batter (no idea where it is from, it was laying around). The whole assembly can come out for charging or you could cut a hole for the usb-c charger and glue this in place.
I recommend doing 2 wall thickness and about 20-50% infill to make the bottom a tab heavier. The lid may have trouble staying on if the tolerances are not perfect. This design is a mess of polygons and far from my best work, sorry about that lol.
