A simple model I made while practicing using Tinkercad. The goal was to make a simple, easy to print, friction fit cigarette pro that would print on a non multi material printer.

I recommend printing with PLA, as that has a bit more give for friction fitting the two models than a more durable material like ABS or PETG. You could probably print it with TPU, but nobody wants a floppy ciggy!

The model does not require supports. Make sure you print vertically, using a brim to make sure it doesn't fall over.
