WYZE filament run-out sensor

thingiverse

FIlament runout sensor utilizing a WYZE door prox sensor. This design utilizes a spring and M8x3 magnet to trigger the switch. Trigger distance is determined by the strength of the magnet, some may be a little weaker or stronger than others. If this is the case either sand down the plunger body so it recesses inside the main body more, and thus closing the gap more. Or if the sensor is too close, dab a little scrap plastic on the plunger end with a lighter and wad it up will the length is correct sand as necessary. The bucket has a m3 hole that you can put a long m3 bolt in to pull the bucket back to allow for easy filament swaps. Ive also included 2 different back plates, one that is a small plate and makes the sensor its own thing, and another that can mount to a pegboard. I use the pegboard one because of how my printer is setup. Parts required: WYZE door sensor (peel off the sticky bits on the back) 3x m3x10 bolts 2x m3x30 bolt 1x spring (the one I used came from an assorted spring kit from homedepot) Feel free to remix this for a different spring, or the actual WYZE magnet that comes with the sensor. Printed on a Qidi x plus at .2 layer height in PLA. Some sanding may be required to make everything fit correctly. Print the file bucket so its standing upright and the body on its flattest side so the layerlines of both parts are in different orientations to prevent binding.
