Creality Falcon A1 Calibration Tool

You don't know where to put the little stair that comes with your laser engraver? Search no more! 
just grab 3 8x3mm magnets and stick this print to the side , always handy

pla , petg , abs , some leftover from last dinner , can be printed in every material :D 

(my suggestion is use it as a purge for other models)
