Lost one of the legs to our VINTEFINT Christmas tree from IKEA - so I reverse engineered and printed the 4th leg and saved Christmas🎄.

Leg is printed out of PETG with 0.6 mm nozzle - I have not retested with different nozzle types, I'm sure it would work fine with 0.4 mm nozzle and PLA. Make at least 1.6 mm wall thickness.

The STEP file is included in case you want to adjust the fit or add a raceway for wires up to the center of the tree.
