Is anyone having success printing keycaps with filament?

I printed a few for a friend. They seem to work just fine, but if you look close you can see the ‘terraced’ steps in the printing. Probably feels a bit rough. I guess you could smooth that with acetone vapour and ABS filament if so inclined.

With an ender 3 it's easy enough, but it does not feel as nice as shot ABS plastic caps.

I am sure though, if you spent time polishing and painting the surface it would feel much better. It's still similar plastic after all.

Biggest problem for me, if printed in PLA the + shaped slot eventually gets too loose and the key pops off. Can just print another but it's annoying for sure.

Resin printers would likely have a much nicer out of the printer feel, with much smoother details at that size (for caps with 3D details on top). You could also print a whole set much quicker. Same speed for one cap as it would be for 100 at once.

I've been using a PLA space (1U) key for over 5 years without any issue.

I think I printed the top at a smaller layer height.

https://youtube.com/watch?v=Grd_a4oi7qU is a really cool video where someone builds a computer that looks and feels like an early Apple design concept for a flat, portable Macintosh, something between a modern laptop and a tablet. They pull it off really well; if you didn't know better, you'd think you'd found a lost prototype. Anyway, one of the problems they had to solve was the plastic colour, and they did it by painting the case. With this new filament they wouldn't have needed the paint. :)

Did you make a full backup of that old SCSI device to modern devices? What did you do with all of the extra space as I can only imagine how small the old SCSI device was compared with modern media sizes

Yeah, the drive was 20 or 40 MB, I think. Easily moved it all to an SD card. If anyone cares about old shareware game source code, I used the opportunity of recovering some old code to create a number of disk images (that you can mount from a modern Mac emulator like Basilisk II for example). Here is one (I think you can find the other three or so from this one): https://github.com/EngineersNeedArt/SoftDorothy-Unfini…

Those screenshots make me miss Glider and Pararena. My brother and I used to be *so* competitive with our Glider scores.

Thanks. Do you have any suggestions for printing the glyphs on the faces/sides?

Very cool! Spent many an hour playing the original shareware glider.

The Dorthy soft/Kansas connection makes so much sense after reading the Github repo. The logo was burned into my brain. I was always nervous about starting the game in front of my parents, but it turns out my dad was really good at glider.
