Duplicator i3 Plus spring retainer

thingiverse

I've got the PowerSpec branded version and it's not living up to expectations. The bed wobbles, shifts, and has too much bounce due to springs that are too loose at their lowest z-stop position. This causes the bed to rise and everything becomes locked in place. To fix this, you'll need to drill out the center of the retainer using pliers to hold it steady while a drill bit runs an M3 screw. The goal is to get the spring to hug the bed screws as closely as possible while still allowing for some movement. This adjustment also allows me to tighten up the springs with just a little room left over for further tweaking.
