Three of these bumpers hold the 120 mm glass and build plate steady on a Monoprice Mini Delta. Bumpers prevent bed from shifting horizontally. Scale to fit, (A 64 mm wide part printed at 62.5 mm on my MP Mini Delta.).
Additional: Fixed MP Mini Delta size issue using Gcodes M92 to raise XY&Z stepper values and then M500 to save. 64 mm model then printed accurately. Original values were 56.5 steps per mm and new values 57.6. Also needed to adjust end stops within .1 mm before getting decent first layer. Calibrating Extrusion was next as 100 mm of extrusion only gave 96. Used M503 to view changes.
