Ear hole expander

thingiverse

You can purchase these items at tattoo stores, but occasionally they attempt to swipe them. On eBay, they are reasonably priced; however, if you dislike waiting for two weeks, this is the solution for you. Printed in "vase mode" with a 0.5mm nozzle (not ideal for the task), the object is created as a single, continuous layer, resulting in an expander that also functions as a screw. The base is intended to be removed, but the decision is ultimately up to you.
