A round, parametric plug that can be used to plug a hole. I printed these in TPU to plug some unused predrilled holes from the factory on my car rooftop tent.

The premade print profiles are only for PETG and PLA since there isn't a premade preset for TPU. The PLA one should print fine for TPU but turning off retraction is recommended. Each build plate has a different pregenerated plug diameter that is labeled in the object name so you can print the size you need.

The Freecad project in the model files section has a Spreadsheet with diameter and depth values that can be adjusted to fit the hole.
