Creality Ender 3 Max z-stop adjustable bracket - no new hardware needed.

The Ender 3 Max is a cracking printer and a good step up from the previous E3's but despite pre-release feedback Creality for some reason still went with a fixed z-stop. The go to fix for this is to swap out the two bolts holding the z-switch bracket to the frame with shorter ones going into t-nuts like the previous versions of the range had but if you don't have those extra parts to hand that's no help.

This bracket is a modded version of the stock one, I've moved the mounts for the z-switch down about 1mm and added a long slot for the stock bolts to go through, I think overall this will add about 3mm movement in the negative direction meaning the bed springs can actually be compressed a bit rather than as some users have reported leaving them so loose that the thumb-wheels can actually vibrate clean off.

This is a first draft / proof of idea, by the time I actually got as far as designing and printing it I'd fitted BL Touch to my two Max's so I can't test it fully, I've passed the design onto a couple of people who have bought a Max and then run into this problem but I'll be relying on feedback from anyone who prints this as to how well / badly it works so I can improve the design.

It's oriented so it doesn't need any supports.
