Etymotic HF5 earplug stub

thingiverse

I want to use my custom etymotic earbuds as hearing protection without risking damage to the electronics of my hf5 earbuds. This proposed accessory should fit snugly inside my earbuds where the hf5 would normally reside, allowing me to easily insert and remove them as needed. Furthermore, there is a convenient lanyard loop that enables me to secure these together in one go.
