Level-supports
thingiverse
I made this simple object in Tinkercad. Edit it online at https://www.tinkercad.com/things/28WhTBffWZZ. I created this model to support wooden pieces that I needed to sand and level. Having a flat bottom side allowed me to level just one side of the pieces. Now, I've found even more uses for these supports: I place them under plant pots to keep air circulating underneath and prevent rot when I overwater them. I'm also using it to support my Mac Mini, which cools down better as a result, and even for my notebook when it's on my desk. You can scale this model and customize it in Tinkercad to fit your needs. I hope it saves you some time - about 30 minutes or so!
