Retractometer Cr-10s Pro

thingiverse

This is a visualizer for observing the flow and retraction of Filament - by the way it cleans and guides the filament. I built this to determine if the retract setting from the slicer was accurate in reality. I wanted to get a clearer understanding of what's happening while printing - now I can see the retraction very clearly. If you adjust the pointer slightly to the right, you'll see the flow. If the waving cat effect bothers you, you can lock the Pointer horizontally - it will still guide and clean the filament. To assemble this visualizer, you'll need one M4 screw as an axis for the pointer and a small piece of sponge - cut the sponge in half but not all the way, leaving about 5mm uncut. The little clips can be adjusted to set your retract marks. This is a work in progress, with plenty of room for improvement...enjoy
