A switch mounting bracket for the z-height switch. GeneralRulofDumb's concept for easing the adjustment of the z-height is great, I like having the adjustment inside the machine. The ones outside interfered with my filament spool, and I had to remove them for transport. But, I did not like the idea of drilling a hole in the frame. So this is a bracket to mount the switch to the existing slots using one of the mounting holes from the switch and another in the bracket for the switch. Both holes have a recessed nut to secure the switch and bracket to the frame. Also, it is not need to remove the leaf-spring of the end-switch.


Place the switch in the bracket and position the assembly to the left using only the hole on the right of the switch and use the original mounting slot on the left in the frame. Put a M3x20 screw all the way through the switch, into the nut. The other screw hole in the bracket aligns with the mounting slot on the right, again using an M3x20screw, don’t forget the washer on the outside of the frame. Use the original 'Ultmaker Z-axis end-switch fine-adjuster' by GeneralRulofDumb, the stl is also included here. I’ve left, plenty of room inside the block to account for different printers, but it does make it fiddly to align. I found the original hex tool by UM inserted from the outside the frame all the way through to the nut helps to align.

very nice, thank you for this great design. i will post my print later. Next step: Thumbscrews for the z-tilt of the print bed.

Thank you so much! This thing really helped me a lot :)

From a German to a Swiss: I love your cheese and this thing! It's really the best addition I've recently made to my Ultimaker - thanks a lot, great idea! P.S.: I second your thoughts about holes :)

This is just the design I was looking for!

Awesome, now Z adjustments are even kinda fun :)

Thx, glad it worked for you.  I intentionally made it a bit narrow so the switch would be pulled against the frame and not the bracket, maybe it was a bit much for yours.  Wouldn't want the thing pushed up.

Very nice parts. My Z-axis switch is a bit thicker so I had to support the gap on the other screw with a small nylon washer.

holes must not be wasted! we swiss limit our holes to cheese and mountains.

what is wrong with drilling that hole on top? The whole frame side is a swiss chees with all the nuts and bolts, one extra will not be seen anyway.
