Note that these guides are designed for springs with an outer diameter of 8mm.

Why?

The original compression springs on my Ender 3 Pro print bed mount were buckling.

To ensure that the springs stay in shape while being compressed I made these guides.

What does it do?

You should end up leveling your bed less often with these.

Post-Printing

Cut the M4 thread / check the holes:

Use a wrench (size 12) to hold the upper guide in place and screw a M4 bolt through it. Do this with all four upper guides. Now take your lower guides and check if the M4 bolt goes through easily. If they don't widen the holes until it fits.
