This stand holds up to 15 toppers up to 28.5 mm...(((((Attention))))) due to the nature of 3D printing there may be artifacts or blemishes on the surface of items and these items can be sanded down very easily if you choose to do so.
It''s we'll made 3D printed product. I like how durable it feels. It holds up to 26mm atomizer, which is what most people would have. I wish it held 30mm, but they have other products that do. Shipping was quick. I will be ordering other items from Standup 3D in the future!
