DIY watch battery replacement. Once you manage to get the watch open and replace the battery, getting the cover back on isn't trivial without proper tools. This non-parameterized example was knocked up in about 2 minutes to get me out of a pinch after I volunteered to fix my wife's watch. The crystal face of the watch protrudes so this die simply protects it by supporting the watch by the outer rim, just apply force (steady, controlled and orthogonal, like a clamp or vice - not too tight).
