This model is a sleeve modeled to be used with cheap LED candlelights and this traffic cone https://www.printables.com/de/model/542796-traffic-cone/comments scaled to 50 mm.

Not much to be done here except glueing the traffic cone to the sleeve with superglue.

I printed them in PLA with the sleeve hole facing up, manual supports for the “roof” and PETG as the top support interface material.

0.2 mm layers, 0.4 mm nozzle.
