End of Filament Switch for Raspberry Pi

thingiverse

Getting crazy with your end of filament sensor is a major hassle, making it difficult to get the filament through. Want to add an external filament sensor for Octoprint or for multiple filaments? Here's a solution that's easy to assemble - no screws required, just some glue or even no glue at all, and bad prints hold without any issues. The filament won't get scratched and hard-moving filament is a thing of the past. The parts fit perfectly together. I've tried it on two 3D printers with great results. What you need: 1 Microswitch (Winomo / Type: 10T85 (GSFY-10)) 2 Wires 2 Dupont plugs or similar (I used some ESP8266 soldering connectors) How to use: Push the knob during filament feeding and release it when it's gone through. All STL files can be modified. Feel free to create a nice remix on them. 08.11.2020: Update - added screwable version: What you need: 2 x M3 nuts 2 x M3 screws I was too optimistic thinking glue could win the fight against filament pressure... it should be history now. 09.11.2020: Update - added housing/mounting case: 0° and 20° housing to fix on the printer with a M3 screw All printable without any supports (check out the pictures).
