PrintrBot Jr. - Print Bed Adjustment Knobs and Pegs

thingiverse

To prevent my PrintrBot Jr.'s print head from colliding with the screws on the print bed's top, I devised a solution using these components: adjustment knobs and nuts. Firstly, I inserted the nuts into the middle of the knobs, securing them with super glue (big ones in front, small ones at the back). Secondly, I modified the provided screws by cutting off their heads, turning them into threaded rods, and affixing them to the bottom of the pegs using super glue. Next, I wrapped the top of each peg with a tiny piece of blue painters tape and inserted it into the print platform's holes. Lastly, I adjusted the stock springs to obtain sufficient clearance beneath the print bed, avoiding contact with the screws holding the entire structure together.
