Clog Detector

thingiverse

This handy gadget lets you catch if your 3D printer's nozzle gets clogged right away. Clogs are rare, but when you're printing big objects, getting notified fast can save a ton of time. It sticks to the top of your extruder using strong double-side tape and hooks up to the hotend fan's 12 V DC rail. I built mine with ABS to keep it from warping due to heat since my Prusa is sealed. Be sure to check out the description for the full list of parts you'll need!
