Sharp MZ 700 Key Post

Here I have designed a key post for the Sharp MZ700. I recently bought this computer with a broken key. The key had snapped off at the keypost fitting leaving the broken bit in the key.

The first design is a standard keypost which fits the keys perfectly but the broken key had the top of the keypost superglued into place! so I designed a second keypost with a 4mm diameter top.

I very carefully drilled into the key with a 4mm drill and it worked perfectly when fitted.
