Universal PTFE Strain Relief

A simple curved spring that refuses to let a section of tube bend too sharply.

• Does not require supports

• Please print 0.2 layer height

• PETG preferred (PLA can work but way more rigid)

• Please print HOLLOW (0% infill)

• 2 or 3 walls.

Designed for 4mm OD PTFE tubes. It should not grip too tight or too loose. If it needs modification, let me know in the comments as I check regularly.
