Magnetic Cat Door replacement key

thingiverse

This cat collar pendant works alongside our magnet-activated cat door. Purchase replacements for around $5 each including shipping or print your own at just $1 per piece. The design accommodates two 1/4" diameter x 2/10" thick magnets. During printing, pause the process at a z-position of approximately 12mm, insert the magnets, and continue printing. K&J Magnetics is my source for these parts (part number: http://www.kjmagnetics.com/proddetail.asp?prod=D4H2). One image shows a notch-less file to demonstrate the internal magnet cavity. Print with a raft due to the small surface area. Utilize Jetty or other firmware upgrades for z-position pause adjustment. I use a Thing-o-matic with a mk7 extruder, employing brass and aluminum which don't affect the magnets during printing.
