FT-5 Bed Level Knob

"Press Fit" knob that the original "knob" goes into. I use press fit loosely, the idea is to gently tap it into position so that it holds tight and the grooves on the original "cut" in, securing them. Add a drop of super glue if you choose for further securing.

As suggested by Zapta: another way to insert the original knob is to use a soldering iron to heat it up while pressing it into the oversized printed knob.

Designed because I have fumble fingers anyway, and those tiny friggin knobs that come standard with the printer SUCKED. With these knobs attached I can adjust each screw with one finger, and not knock the bed completely out of whack while doing it.
