#Loopkey
I’ve been working on a captured loopkey design recently:
I should probably stop spamming the general printables thread, so i’ll put updates here.
V2 action video (0.20mm gaps, loose sliding fit):
V3 action video (0.15mm gaps, w/ XT90 installed):
Disregard half the connector moving, that should be epoxied in place in the final version.

Symmetry all the things
Hidden slider design - not visible once closed
Started adding some ergonomic curves. Shoutout to @glyphiks - totally stealing/evolving your nice mounted loopkey design.
Improvements:
- M3 nuts drop it well, and are captured nicely after connector install. Happy with that.
- Sliding action is solid now
- XT90 fit is very snug (difficult to remove short of pliers)
- Thumb hole works nicely
- Can now be printed at 0.20 layer height with zero support! Huge improvement here. Slider gets printed horizontal for strength in the arms, mount gets printed vertical to get a clean internal cavity (brim recommended on this part). Easy to knock out a set in 3 hours.
To Do:
- Detent to lock out at full-open did not work. Probably need to make it bigger and engage sooner.
- Need to increase the male-female gap at full open for safety. Maybe 3-4mm additional.
Will dial in that detent and make it pretty. It’s well on its way to usable. Sounds very satisfying too.
