Recently I have been glueing a load of kensington lock plates on to stuff so that folks don’t wander off with them. Admittedly these aren’t going to stop folks actually stealing them but it stops casual theft and ups the level of mental criminality. These little things are expensive and turn out to be rather difficult to find to purchase in the UK. So what to do? Yep you guessed it print my own. So fire up the 3D modelling software which we just seem to have about and make a model.

There is no real world measurement in the software so the first prototype is a bit on the big size.

What I made next to what I was after. Obviously way to big. It also occurred to me that the ends were round for a reason, ie corners are easy places to get leverage to ping it off.

An here are the final results. In the first the hole is a little to big and not deep enough. The second is pretty close and needs a tiny adjustment and its ready to go.

And here a few printed at different fill densities stuck to the side of a cupboard for testing.
