This print originally inspired by PRNTR3D's “Beautiful Christmas Ornaments - Vase Mode Easy Print” on Printables. It's intended to be two-color for a multi-extruder printer, and is more challenging. Originally printed on the Snapmaker J1s IDEX in Dec. 2023.
Two, thin spiraling lights surround each other as in an embrace. This model is provided as two merge-able bodies for easy tool/color assignment.
There's a hoop in the “top” intended for threading a 3 mm (1/8") wide ribbon for hanging. May need tweezers to pull it through due to catching on the layers.
The ornament is intentionally delicate, so care must be taken as it grows from the build plate towards the tips. Before they connect at their tops, the thin spirals can be springy and start to wobble, so selectively slowing down for these parts is helpful in getting a clean result. (See recommendations and video below.)
For an overly detailed look at how I sliced and printed this while beta testing the Snapmaker U1 (Sept. 2025), see this video:
Slicing recommendations:
- Layer height: 0.2 mm
- Import/merge two parts as one object, assign to tool(s)/color(s)
- Looks lovely in silk PLA
- Need clean, string-free retractions (e.g., as seen on a spire test)
- Speed modifier objects on at least the top ~20% of each of the inner and outer parts to reduce all print speeds to 10-50 mm/s as it approaches the tips can prevent wobble and improve print quality.
- YouTube video above shows example using Cone modifiers in (Snapmaker) OrcaSlicer.
- Small extrusion/perimeter speed and/or minimum layer time can do similar, but might not hold up if duplicated, or for the inner part. Modifier objects are preferred for direct control.
- Or I guess you can just print the whole thing more slowly. :-/
- The base isn't exactly small. Still. Depending on printer, brim or bed adhesive might help as some spires may spring/catch and pop it from the build plate, depending on printer and slicer settings. (I lost one on the J1s.)
- If you end up with stringing do not try to remove strings with heat. It's very thin in places, and even short contact with a heat gun is very likely to deform it.
(If you can print this cleanly at 300 mm/s, please post your make and brag about it. Personally, I dare not try!)
