Anycubic i3 Mega - Z Endstop Support

thingiverse

My Z endstop was consistently bending downwards, leading to numerous issues both subtle and dramatic. 1) The height of this block is specifically tailored to my printer's bed height, nozzle length, and Z endstop screw adjustment, which may not be accurate for all i3 mega printers but should be close. However, adjusting your Z endstop adjustment screw can compensate for most small differences. 2) Anycubic-supplied endstop switches have two vertical screw holes, whereas standard reprap style sensors on eBay usually feature two horizontal screw holes. I used four M3x8mm screws to mount it, as mentioned in the comments. Pairs with this mirrored left side mount: https://www.thingiverse.com/thing:2763895 I haven't used these for months. For your own sake, flash firmware with dual Z endstops and print two endstop brackets for that setup. Printing with only one endstop on a mega is masochistic – don't do it.
