Candle stick with an inner diameter of 23.5 mm. It is a little fragile but liked the design.

Printed with following parameters:

• Resolution:    0.2 mm
• Infill:               50%
• Fillament:      PLA
• Raft:               NO
• Supports:      NO

My printer could print it without supports but it is on the edge of what is possible. Be aware that it could fail at your end.
