Hey you guys! I’ve been working on a new shipping puck that can hold 30+ seeds and is able to close with a lid while maintaining a low profile.
The puck is 4.25 mm/0.167 in. thick when assembled with the lid, the same height as the pucks developed by the wonderful @Mr.Sparkle. It is 32 mm/1.26 in. in diameter. The lids snap on and the puck is divided into four, providing structural support. In my limited stress testing with the model printed with PLA+, these pucks are very rigid. I would recommend printing the first layer height at 0.10 mm. Please let me know what you think or if you run into any issues.
