Remix of the Original Prusa i3 MK2 extruder body and cover.
The problem that orginally spurred this project http://shop.prusa3d.com/forum/prusa-i3-kit-building-calibrating-first-print-main-f6/-hump-in-bed--t2668.html
While waiting for my replacement bed from Prusa, I acquired a 2mm aluminum sheet and used heat tape to attach it to the heatbed, placed a new PEI sheet over this and a lot of the issues I had were minimized. There were a few spot and they would still show on larger prints, not bad enough to ruin the finish, but still noticeable. The other problem was my PINDA probe was very close to the prints, I'd say about ~1mm above, LiveZadjust at about ~.15. I've already broken the probe holder on a stray piece of PETG. Luckily I was able to attach it long enough to print a replacement body.
Anyway, looking to try a 1/8" piece of glass attached to the heatbed to see if that will fix the surface issues that I have. Ordered a BLTouch probe a few weeks ago and have been figuring out how to mount it, how to wire it, what needs to be changed in the firmware, etc. This is the first iteration of the mount. I have not had the opportunity to mount it yet, that will come after I figure out the wiring and firmware side of things.
