I was tired of my tiki torch poles falling over, so I created a two part mount. The dovetail mount has two countersunk screw holes that fit wooden decking screws (among others I'm sure).

Print the mounting piece flat, cup as is. I printed the mount at 100% infill with 4 walls (to resist cracking while screwing), and the cup at 15% gyroid with 4 walls.

Just print the pieces, screw the mount to the post, slide on the tiki torch cup, insert torch. Please note the stoppers on both the cup and mount. Stopper on mount needs to be on the bottom of the post or the cup will slide off (see pictures if unclear).

Recommend an outdoor-hardy filament (pictures of model in PETG).
