Update (Feb26): Left handed thread (original) now supplemented by a right hand threaded lid (new) - as suggested by several comments from makers. Feed back appreciated, ta. Whether you are left or right handed you can choose a top that suits.

A simple 2-piece case with a rotating click-lock closure and provision to add a lanyard. The lid has vent holes to keep your plugs ‘fresh’ this also allows the base and lid to both be threaded on to the same lanyard. Ideal for a motorcycle jacket pocket.

For standard foam earplugs

Printed in PETG. Will print without support but I found that the lock tabs and recesses benefitted from enforced support (included in the BGcode). GCode prints the RightHand Thread version of the top. Just need to make sure you clean out all supports to perfection!

If you fancy something a bit more flashy, try the clam-shell magnetic closure version.
