Geeetech i3 Pro B extruder wiper

thingiverse

This is an extruder wiper. I created one because cleaning the extruder with tweezers before each print was a huge hassle, leaving strings everywhere. So, I borrowed an idea from the Cel Robox and designed a wiper to clean itself automatically before each printing session. You can see it in action here: https://www.youtube.com/watch?v=17oLfm5vTJA To make the wiper work, I used heat-shrink rubber that had been preheated until it reached its maximum shrinkage point. I've also included my start script, which includes a pre-print line to ensure good plastic flow at the beginning of each printing session.
