 I wondered if it was easier to use the tweezers with a reversed action, where applying force releases the object. And by default it holds the object. For this, I used this [mechanism designed by Devin Montes](<https://www.myminifactory.com/users/MakeAnything/collection/compliant-mechanisms>) \- [video](<https://www.youtube.com/watch?v=PgDJlLqeTdo>) and transformed it for the tweezers.

 I used Cura to make toolpaths for my 3d prints. I uploaded my stl files, set my machine, choose PLA as my material and used these settings:

 I used an [Anycubic Kossel Plus 3D printer](<https://www.anycubic.com/products/anycubic-kossel-3d-printer>) to print with a black 1.75mm PLA filament.

-Printing the gemclip: The finish was alright, as the first layer spread a little too much, causing it to be broader then the actual form. The first layer has a layer height of 0.3mm, and all the consecutive ones were 0.15mm. I used a cutting blade to finish these edges.
