PrintrBot Jr. - Print Bed Adjustment Knobs and Pegs by phraust Feb 12, 2013

Description

My PrintrBot Jr. print head was bumping into the screws on the top of the print bed, so I put these parts together to fit in the holes and not interfere with it's operation.

I also wanted an easy to adjust way of leveling the print bed, without having to fumble with those damn little nuts.

Great idea with the countersinking! I'm thinking about upgrading from the laser cut wood bed to something metal or glass, just need more material! :D
These work nicely. Thanks. To solve the problem you are talking about, i used a flat headed screw on the print platform, and countersunk it in. No more bump.
I ended up putting little wingnuts under my jr, but I like this idea. Im gonna give it a go.

Instructions

  1. Print it out, I used PLA.

  2. I just popped the little nuts into the middle of the adjustment knobs, and used a drop of super glue to keep em in place. (Big ones go in front, small ones go in back).

  3. I flipped the screws that came with the PrintrBot Jr., cut off the heads so they were more like a little threaded rod, and super glued em into the bottom of the pegs. Then I wrapped the top of the peg in a wee little piece of blue painters tape, and stuck it em in the holes of the print platform.

  4. I found that by stretching the stock springs out, I could get the clearances I needed under the print-bed, to avoid rubbing against the top of the screws that hold it all together.
