Anet E12 Leveling Spring Caps

I've made these to be used with an Anet E12 springs on the bed levelling.

The 2.5mm hole spring caps are for the top and can either be tapped out M3, or just screw an M3 countersunk screw through them. The 4.0mm holes are clearance and go on the bottom of the spring.

I've used these with M3 x 40mm countersunk screws so there is plenty of screw for the adjusted to connect to.

Once done up, the spring seems to hold to the top and bottom caps and they don't fall off easily. Handy if you take the heated bed off the printer.
