Geocache Preform Dispenser
thingiverse
This mechanism releases a bottle preform in an electronic gadget cache. It uses a 9g servo (SG9) and 4 screws 3.5 * 16 mm. The box can be glued to the mount. And this can be glued into the birdhouse. Super glue (cyanoacrylate) works very well for PLA. Epoxy should work also. The spring is derived from “Accordion folded customizable spring”. https://www.thingiverse.com/thing:980377 Accordion Length 52 Accordion Folds 20 Accordion Width 11 Accordion Height 11 Accordion Sheet Thickness 0.5 Accordion Right Angle Ends: To both sides Reinforcement For Ends: No 1-hole Hole 1: Circle Hole 1 Diameter 8 Hole 1 Rotate 45 Hole 1 X Position 0 Hole 1 Y Position 0 Video: https://youtu.be/XtjUOcepa-8 “Behind the Cache” made a birdhouse using this mechanism. https://youtu.be/C2H1XU1Sllo
