This is a tealight holder printed as a single part. You pause the print to attach the curved pieces, then start it again to secure the pieces in place.

This means you have no filament waste and it can be printed on a single colour printer with a single filament swap.

I have attached the stl and the Bambu 3mf which should include the pause.

It's best printed at 0.2mm layer height

You can see how its done in the attached video.
