ProMega Mirror Bed Bumpers

thingiverse

These clips are designed to give good stabilization to a 1/4" mirror bed added to a ProMega. If you are using aluminum or other bed materials some of the heights may need to be adjusted to ensure that the clips do not interfere with your print head. Double check them on install and make sure that nothing is in the way. The rounded bumpers are designed to press the mirror forward and to the left to keep it locked in while allowing easy, drop-in removal and re-installation for cleaning and coating with hairspray or whatever you use. <p> Print one of the two front bumpers and two of the rear one which install onto the two pairs of M3 holes in the back frame piece on either side of the heater connections. <p> You will need 4 M3-18 countersunk screws (though mine aren't here yet...). M3-20 hex head ones work and at least on my printer are not in the way of anything if you lock them down.
