Davinci Bed Level Screw (No nuts required)
thingiverse
I adapted some other ideas from Thingiverse and tweaked them since I didn't have any M3 nuts handy. I printed these in PETG plastic, so keep in mind that ABS may require a higher or lower size percentage for shrinkage as PETG has very low shrinkage. Just print them off, then remove the screw dial from your print bed and tap (using a hammer and punch gently) them into place until they hit bottom and replace the screw dial! It's a simple and nice-to-use process. I've uploaded the STL and SolidWorks file if anyone wants to customize or make adjustments.
