I order this before my last rip and it showed up while I was gone. It's a SCRIB3d. Hand held extruder, you can adjust the temp from 180-230 degrees and can adjust the extrusion speed also. I got it to do touch up on project but also to use it to fasten together parts that were printed separately. It uses 1.75 mm filament and has a .4mm nozzle. I haven't used it yet on a project.
