Jetpack piano keys. What, where, how?

[JSmails]

Hello I'm stuck.

I'm trying to get my head around the piano keys on the jet pack. Does someone sell these in resin?

Also, what are the dimensions on them? And if anyone has built them before, what do you make them out of? I tried wood but they are too small and keep splitting off. Foam maybe? I imagine I could do cardboard with the right dimensions.

So small and the angle on them is hard to reproduce every time without using a saw. I imagine grinding would be easier to get within a degree or two on each piece.

What have others used?

Thanks very much!

Post 14 in the link shows how Matty Matt did it. I can't answer the rest of your questions.

He used a paint stirrer cut in half length wise with a bevel on one edge it looks pretty fantastic if you ask me.

I molded a cap from a set chisels I had that looked like these

I used one from a smaller chisel and made a quick mold then cleaned up a cast (removed made in USA, cut off top rim, cut to size) then molded again and cast up what I needed.
If I still had the mold I'd help you out but its long gone.
Maybe it will give you an idea if nothing else though! Good luck!

Thanks for the answers! I haven't ever seen Matty Matt's build before. I'll have to read the whole thing.

I should have read it before I started. It would have saved a LOT of time.

I got shape ways 3D printed piano keys for my custom MOW pack.

They seem small at first, but they fit just right.

Oh wow that'd be a good idea Lynn. Thanks for the links!

Sadly I want to get this thing done this week or next and the keys wouldn't ship until the 16th.

I'll likely give the paint stick a try and if that's too frustrating I'll Shapeways the keys.

If anyone else has suggestions, absolutely speak up. Thanks for the replies so far!

My Boba jetpack I made the piano keys using pepakura. I folded & glued the pieces together making a shell & filled them with a glue/spackle mix. Letting them dry then sanding them square. I didn't really give a good work in progress photos of them though.

Here are the pep files in letter & A4 formats you will need the Pepakura viewer to open the PDO files. The PDF files can be printed at 100%.

Wow. Thanks! Pep files make a lot of sense. I'll definitely give this a shot tonight!

Oh man, thanks for bringing this up, I too was looking for keys for my jetpack that I am working on. Thanks so much for the links!

I'm 3D printing them, I modelled them myself.

Great job with the piano keys. It always bothered me how the MOW pack only has 3 on the center tube when there should be 4 of them.

Cutting out and super gluing them all was tedious and time consuming. But incredibly cheap and very close to accurate.

Thanks for those links.
