Our floor isn't level, which means our table isn't level, which means our printer isn't level. It's close, but even with assisted leveling of the build platform our prints had regular curling and peeling, raft or not. I modified this Thing and made some nuts and bolts from this Thing and was able to make adjustable feet for my printer. After leveling the printer itself, and then doing assisted leveling for the platform, our prints are now pristine works of uncurled PLA mastery.
For each foot, print the following:
- 1 bottom
- 1 top
- 1 bolt
- 2 nuts
I recommend that you print the nuts and bolts separate from the tops and bottoms. The tops and bottoms can be done at 0.2mm layer height, 2 shells, and 10% infill. The nuts and bolts are the load-bearing pieces, so they should be stronger. I changed infill to 25%, and that seems sufficient.
Assemble each foot as follows:
- Slide a bolt through the bottom so the hex head is flush in its receiver. The bottom piece is the shorter of the two.
- Screw a nut down over the bolt to hold it in place. This step is optional, but I felt better with the bolt being securely attached to the bottom piece for load distribution.
- Screw another nut down over the bolt. Make sure that this nut does not touch the first nut or else you might unscrew both nuts when adjusting.
- Drop the top piece over the top nut so that the nut is inside of its receptacle. Adjust the height so that the tip of the bolt is just beneath the top of the assembled foot.
- Repeat with the other three feet.
- Gently place the feet under the corners of your printer.
- Place a level on the printer floor, not on the build platform. Adjust the feet until you have the bubble centered from left to right and front to back. You can (and should) adjust the feet without removing them from under the printer.
- Once you have the printer leveled, continue with assisted leveling.
