This is a remix of the other filament Guide. I didnt think it was necessary to have the holes counter sunk, and the z rod have 2 different sized holes. I just made it all the size of the big diameter. I made 2 of the original before and found it hard to remove he supports, and clean out enough of the material for it to sit right over the brass lead screw nut.

The holes for the bowden tube are 4mm. I drilled them out afterwards as you will find out. I dont spend a lot of time tweaking hole diameter size to come out perfectly. Every printers different. And its 5secs to ream them out.

I printed with about a 60% infill, as when I printed the original I went with about a 20, and since the holes were counter sunk, the bolts were pulling through.

Can print laying flat if youd like if your gonna ream the holes afterwards anyway. Or on its size, both work.
