Yarn Walking Holder

This is my first real design so please be nice!

I've been seeing these things get popular online but I didn't like that they didn't sit flat when sat down. I recessed the spindle base into the main base and though it doesn't look sturdy it's plenty fine for yarn, even at 10% infill. The hole for a spinner clasp is 5mm and I found that to be a good overall size for most small clasps on the market.
The objects are oriented correctly to print flat on the build plate.

I'm not charging for this design but tips would be appreciated if you like it enough. Please do not use for commercial use, I do not give my consent for this design to be sold physically or digitally.
