Updated version of my original design. In addition to height selection, the customizer now allows text on the body, and optional symbols (radiation or biohazard) on the lid. Also added the option to generate a companion o-ring.

Designed to use an optional O-ring:

AS568 #224, 44mm ID, 3.6 cross-section

Or use the included o-ring and print in TPU. 

Recommended layer height = 0.2mm

Infill 20% or better

No support necessary

UPDATE: 2026-02-25 fixed the text option in the customizer. Should work properly now!
