A simple model easy to 3D print to tie your pants. It's ideal cycling or preventing your pants from wearing out by rubbing on the ground. I printed them with simple PLA material and it seems to be just fine.
This purchase includes all my project files such as: Freecad native project as well as the Blender animation/compositing and video editing file. This could be a great way to learn how I achieved this, from the modelling to the final video render. I did this to make sure that the buy is worth it.
