This is a rolling or non rolling caddy I designed for my acrylic 34 mm diameter bottles of paint. I decided to add nylon transition bearings (optional), so it can roll on our kitchen table, when we have paint parties. Easier to pass around the paints.

The bearings are - TOMUM Set of 8pcs CY-8H Mini Nylon Ball Transfer Bearing. A pack of 8 can be purchased on Amazon. If you wish not to have it roll, use the no bearing stl file.

If your printer is good with bridging then supports should not be needed
