Twisting Christmas Tree – Click Detents, 2 Sizes

A tabletop Christmas tree made of star discs that you twist into a spiral – and the spiral stays put.

- Click detents: each disc has a small spring tongue in its centre hole that rides on the flats of an octagonal rod. Turn a disc by hand and it clicks every 45°. Twisted shapes do not drift when the tree is moved or dusted.
- Built-in spacers: every disc carries its own spacer sleeve – no loose washers, nothing to count.
- Locked rod: the octagonal rod sits in the base without turning, so only the disc you hold moves.
- Plug-in star: the topper slides into a slot at the top of the rod – print it in gold, silver or any accent colour.
- Two sizes, one disc set: M ≈ 19 cm uses discs 5–13, L ≈ 25 cm uses all 13 discs. Start with M and upgrade later: print discs 1–4, the L rod and the L base.
- Prints without supports: discs and star lie flat, the rod lies on one of its flat faces.
- Test print included: a short rod, a mini base, the smallest disc and the M star check the click and both fits in under an hour.

Assembly: push the rod into the base, slide the discs on from largest to smallest, plug in the star, then twist.

**Print settings:** PLA, 0,2 mm layers, 3 perimeters, 15 % (Sockel 30 %) infill, supports: No.
