E3(Pro) Glass Build Plate Corner Caps

thingiverse

Simple corner clamp/cap for Ender 3 (Pro) with a glass build plate. Replaces the bull clips that are supplied (and often interfere with hotend when printing larger models) It is recommended that you add a slightly higher (2.2mm) z up to your default start gcode to allow clearance before the print begins in the normal starting position.
