V-Channel / D-Bot USB Vacuum Holster

thingiverse

This is a simple clip/holster to hold a USB-powered vacuum to a 20mm v-channel extrusion, as used on the D-Bot and derived printers. These are handy for cleaning out little bits of plastic and filament that get trapped around the print bed and extrusions holding it, and around the base of the printer. This is designed to hold this particular USB vacuum: https://www.amazon.com/gp/product/B071V7PFCM The model seems to be a fairly generic imported one, and seemingly identical ones are sold by a slew of vendors. That's the specific one I have. These are particularly handy with my D-bot power supply cap with USB power ports: https://www.thingiverse.com/thing:2493619 As a note, you'll probably want to use a rounded-top M5 screw for the top screw, rather than a cap head, as it will keep the vacuum from sitting all the way down.
