Retractor / Lift Spring Arms 15-40cm reach by Kiolia

Last crawled date: 3 years, 1 month ago

Lightweight spring arms for lifting stuff that needs a little upward tug. Designed for extension springs that are about 14mm x 4mm OD at rest; I got mine from a dead printer or something and have no idea where you'd source them. You'll also need a 3x12mm steel dowel and 2 M3x12 grub screws, plus whatever you want to use to attach the ends to stuff (I used paracord).
I designed these to lift bowden cooling tubes, in the completely untested assumption that they'd provide a more nearly constant lifting force over their full range than something elastic; they provide only a very gentle pull, but it's enough if there's a pair of them to make a difference.
Honestly, I'll be astonished if anyone else finds a use for these, but I'm posting them anyway because a) WHATEVER and b) they do look pretty neat compared to a piece of bungee. Beefier versions would probably look hella rad as supports for a flying extruder.
