Manual Bed Leveler

I was having trouble leveling my Ender 3 V2 bed for the longest time. I decided to quickly throw this together to manually level the bed prior to adjusting the leveling knobs. I made two different ones, one for the larger bubble levels and one for the smaller ones. The center bubble level is the same size for both. You can purchase the levels from online at reasonable prices. You will need 4 of the larger (15mmx15mmx40mm) levels OR 4 of the smaller (10mmx10mmx30mm) levels and 1 center level. If you need a bigger or smaller size just make the rails longer or shorter and adjust the placement as shown in the allonepiece files. If you adjust the allonepiece files, your measurements will not be correct as far as holding the levels in place. It is better to change the size of the rails, align them the way you need them and then make it one stl file like I did for printing. Print in whatever type of filament you want. I used PLA with 20% infill. Keep in mind that this should take up most (if not all) of the bed space in order to print. This is designed to level all for sides and the center of the bed, not just the corners.
