Filament Diameter Indicator Guide sensor measurement dial gauge digital
thingiverse
Nifty guide for my hand-held digital dial indicator thickness sensor. Works great for measuring the diameter for 3D printing filament extrusion. The dial indicator tool works OK, but without some sort of guide, the filament walks off the measurement area to one side or the other. This little guide holds the filament in the center of the bearing on the tool. I bought this tool for ~$60 USD on aliexpress. They sell a dongle to connect it to a USB port for an extra ~$20. A think this combination might work well for the thickness feedback loop for your DIY filament extruder. dial indicator tool: aliexpress item 955188460 and the USB dongle: aliexpress item 32502725458
