Spiral / Slinky
Description
####Spiral / Slinky A length of 3D filament from the spool behaves like a slinky, especially the last few yards. If you need a spiral with a thin rectangular profile for a toroflux, try this design. It has a inner diameter of 128mm and a height of 48 mm in 15 turns. There is a 0.4 mm clearance between adjacent layers. It can be printed at 0.2mm or less. Once printed, please pull gently or use a small blade to separate the layers. Be safe! I made the bottom smooth to avoid the use of support. Please cut off the bottom and top layers for a spiral. Have fun! ####References 1. Toroflux using 3D filament. bridgeshttps://www.youtube.com/watch?v=qAuxJVbpGqw 2. Kinetic knots. https://archive.bridgesmathart.org/2023/bridges2023-567.pdf
