I wanted a front sight adjustment tool for my SMLEs, but I didn't want to spend a few hundred dollars on one, if you can find one at all.

But I have a 3D printer...

The first iteration fit perfectly, but wasn't strong enough to resist flexing when tightening the cap screws, so I added a bridge at the top to make it more robust, and it fits and works perfectly.

Not going to be doing thousands of adjustments, but the occasional one here and there will make it worthwhile.

Not bad for 35c in plastic, and few heat set inserts and a couple of cap screws.
