Safety 1st key

thingiverse

Safety 1st replacement/backup key. I printed this at 0.16 mm height. Also keep in mind the bottom of the key is only 0.2 mm thick. Adjust your print settings accordingly. I used some ebay 25x2mm magnets which are unfortunately a little on the weak side. I modified the design so two stack, and I've found that has been enough to trigger my locks. I highly recommend you source good magnets for this project. Superglued everything together, clamp it and let it sit for a day before using.
