Shearwater HUD Protector

Update 22, Oct 2022 - The cap design was fitted with a dedicated slot for the zip tie.

This is the original design for the Shearwater HUD Protector, all the others were very large and clumsy.

I recommend printing it from ASA or PETG with 0.1mm layer size with an external brim, don't use an abrasive material like the XT-CF20, the threaded parts won't work because of the added friction.
