When I first built the i3v, the thing that annoyed me the most was the end stop switch brackets. The geometry of the Y stop seemed strange to me, with the bolt hitting the hinge side of the switch. I couldn't get the X end stop far enough to the right to use all of the bed and I never could get the Z switch to trigger, no matter how much I trimmed the wooden mount.

So, I designed a set of stop switch mounting brackets that solve these problems. The Y switch is reoriented so the ball end of the switch hits the screw. The X stop is turned vertically with a notch in the bracket to fit around the wheel bolt and the bracket has a place to zip-tie the wires. The Z switch is relocated around the side of the extrusion so it lines up with the X idler.

I have downloaded and printed out your X and Y brackets, but I keep having trouble mounting them. It seems I cannot get the screw tight enough to keep the bracket from moving, even after REALLY torquing down on the screw. I think I actually crushed one Y bracket by tightening the screw too much, but it still was loose on the extrusion. I got the X to stay put somehow, but the Y won't cooperate. Any suggestions?

As for mods I've made, I haven't designed any myself, but I've just added this http://www.thingiverse.com/thing:285504 to my i3v, along with the requisite firmware changes. I've also added lights to my printer, both at the top of the frame and behind the hotend.

Your screws may be bottoming out in the V-rail. I noticed that possibility during my i3v build. Look where you've tried to tighten something to the rail. If you see a circle being cut into the bottom of the channel where the nut plate rides, that's what is happening. If so, add a washer under the screw head or file the screw shorter.

I think I may have figured out the problem with this, though I haven't tested it yet. I installed the T nuts as demonstrated in the MakerFarm assembly videos, with the raised threaded part up. I noticed that this threaded part was coming in contact with Clough42's brackets, keeping them loose on the extrusion even though the screws were impossibly tight. I think if I flip the T nuts over, it may work as intended.

The tee nuts only work one way. raised part must be away from the screw head.

Huh... on my i3v all of the T nuts are installed with the raised part away from the centre of the extrusion. I haven't had any problem with them until I tried to use the X and Y endstop brackets made by Clough42.
