This is a LCD housing for Folger Tech 2020 printers or other v-slot rail frame systems. Designed for the 2004 LCD display w/ SD Card reader. Flexible front panel under knob activates the stop switch. Mounts w/ 2 twist lock t-nuts to hold to frame and uses 2 self tapping screws to fasten housings together trapping LCD PC board. Finger access to SD card on side. Spacing under panel to allow free motion of extruder wires.

Updated: Added a larger knurled display knob. Dialing up temperature settings can get tedious with small knob. Offset channel allows easy rotating with thumb. Knurled edges match numerous upgrades I have since made to printer including bed leveling knobs, z axis adjustment knob, X axis belt tension knob.
