Great additional space for unpainted minis. I made it slightly thicker to fit my desk. I also used well dried PETG and near the end the roll ran out so I had to crack open a new one that wasn't dried, but fortunately it didn't affect the print.

Petg with the same profile works fine.

Very easy print with petg on the same profile.

Very good turtle. Printed in white petg with the same profile without problem. Painted still retains the flex.

It's a cube. What did you expect?
