It's a tiny stand inspired by those for test tubes that keeps the individual bottles safe and organised.
I printed it with PLA at .15mm (quality) with 15% infill on a Prusa Mini but honestly you could go much less precise as it's not a particularly complex part (i just wanted it to have a pretty surface finish lol).
this is the perfume set it's designed for but probably works with any bottles that are 11mm in diameter.
The author marked this model as their own original creation.
