Tree Topper Adapter – Keeps the Star Straight on a Thin Tree Tip

This is an adapter for Christmas tree toppers that wobble or lean: it slides onto the tip of the tree, and the topper sits on its outside. Six flexible fins inside grip tips of about 7–14 mm and keep the topper upright.

Outside Ø 18 mm – fits toppers with an 18–20 mm tube

60 mm long with a flared mouth that slides over the needles

Prints upright, no supports

This is the free basic version. The complete set is "Tree Topper Adapters – 15, 18 and 25 mm Sleeves and a 10 cm Tip Extension" – you'll find it in the Layerline shop on Cults3D.
