Yet another sealant cap

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3457239.

Inspired off another design with o-ring, but adapted to available o-ring and preference.

Threads are deliberately a little loose to allow gunk over time. .stp file available for modifications.

I ordered o-rings off ali express. https://www.aliexpress.com/item/NBR-O-ring-CS-3-1mm-x-OD-21-22-23-24-25-26-27-28/32731899167.html
