Anyone for a Brownie? (C64 Brown!)

Started a print tonight! Version 6 🙂

That colour may not look correct but it’s not intended to be perfect,

I need to iterate this process slowly and scientifically so I can recreate the colour at any time.

Best place to start is from a known working point and changing a single variable at a time to get to where you want to be

Here, I’m starting with the resin I know works – drab grey.

I’m adding an unknown if it works brown pigment just to see what happens!

If that prints, I can try adding black pigment to make it darker brown.

If it doesn’t, I can try using a CMYK mix of colours to make the correct Brown

Once I get that shade, I can try different resin bases to see what gives the best finish! Maybe clear + brown or white +CMYK will do the job!

I’ll be iterating the CAD model and the colouring at the same time!

Hopefully this new CAD model will fix the minor offset issues with the keyboard, shifting all the keys slightly to the right also allowing me to finally reveal a working test fit!

One small thing I picked up when test fitting my first attempt, I’d not perfectly centred the left shift key button and Return buttons on the PCB. It doesn’t matter in the grand scheme of things as hacking your own keycaps doesn’t need perfect alignment on the wider keys, only the 1 wide keys

Where it is annoying though is I can’t correct this error or any keycaps I make now won’t perfectly align on old keyboards! Heh, what’s 1/2mm between friends eh!
