Anet A6/A8 Flat Glass Bed holder (optimized for autolevel front sensor support)

thingiverse

This glass holder is optimized for autolevel front sensor mount, but can be used in any situation. When the autolevel sensor is mounted in front, everything goes smoothly except ordinary glass bed clips; they stay on the nozzle's way at the back edge when autoleveling occurs and can be on the sensor's way at the front edge while printing. With this holder, the nozzle and sensor never come into contact. Holders size is tuned for 220x200x3 mm glass and printed with ABS. Holder clips stay about 0.5 mm from the glass plate (usually z offset for sensor is around 1mm), which is safe for the sensor. Don't tighten the glass too hard, just screw the nuts a little, and it will be enough. Autolevel Front Sensor Support 18mm can be found at https://www.thingiverse.com/thing:2067660. No post-processing is required for ABS. Metal parts include two M4 threaded rods 240mm long and six M4 nuts. A nut driver model is included to make it easier to open and close the holder. Use common settings for printing.
