LuerLock Keychain

Added a keychain hole to each side of the LuerLock heads.

In an attempt to make them a little more airtight I dropped the layer height to .12mm instead of .20 and used supports. Printed for flight medicine

My Orcaslicer settings

• .12mm layer height .4mm nozzle
  -Wall loops 3
  -Support - Tree, threshold angle 15

Remix of wavexx M/F luer lock

Their instructions/ information is as follows

Double-ended Male/Female Luer Lock Cap. In the image the red parts are printed in FDM while the blue ones are the original injection-molded part.

Fully 3D-printable in FDM in both orientations, no supports required.
Optimized for a 0.4 nozzle, 0.15 layers or less.

WARNING: the seal likely won't be air-tight due to imperfections in the printing process. Liquid can also penetrate between micro-fissures between the layers. You must consider if these limitations can affect your experiment.

Cooling and material is extremely important when printing this part accurately: PETG or PP recommended. Always print multiple copies to ensure the material doesn't overheat while printing.

Using a SLS/SLA process should result in an air-tight part.

A big shoutout to this page which provided a good basis for the measurements.
