Loki TVA TemPad Printable Assembly
A simple 3d-printable model of the TemPads used by the TVS from Marvels Loki series this includes a solid version in opened and closed state as well as one split into two parts to click together to make it open and close and one in two parts with holes for a 2mm rod though I recommend scaling that up to 150% and using a 3mm rod
