Time’s progressing and it’s still taking a long time to obtain a satisfactory print of my CAD keycaps. Some quotes have come in and…they’re quite a bit.
so, time to change focus for the short term to let me actually play games on the mini with all the keyboardy goodness that a working keyboard will allow
So, on to some butchering
The Plan….create a plaster of paris negative of the original keyboard – to hold the keys straight when attaching them.
Step 1 – Print out the case design from my last post
Fits like a glove……..or does it?
Step 2 – realise that I’m making a NEGATIVE and the keyboard needs to sit INSIDE the box, ‘upside down’ Redesign and re-print…
Step 3 – Coat liberally in spray oil… Wife wasn’t too happy that I’d used her pricey artisnal olive oil from our trip to Italy, nothing but the best for my Mini though………
Step 4 – Knock up a batch of
pancake batter Plaster of paris…About 50 grams of powder and 60ml water worked for mine….not too viscous.
Step 5 – Fill up the mould
Screw on the keyboard – making sure the keys are aligned and straight with the F Keys and wait overnight…
Use the holes either side to top up the plaster so it overflows a little
Give the whole combo a dozen or so short sharp drops / knocks on the table to free up any air bubbles
