Picture of manufacture custom gears with a craft cutter and shrink plastic
Update:  wow, bummer.  I just found out that ProvoCraft (the makers of the Cricut)  sued "Make the Cut" and "Sure Cuts A Lot" so that they can no longer sell their products to work with the Cricut.

Here are some competing products which can be used with Make the Cut software though I have not tried these products specifically, they look like they do about the same thing

Klic-N-Kut computerized craft cutter
Pazzles Inspiration amazon
BossKut Gazelle amazon
USCutter MH/Lazerpoint
 





Step 1: Materials

for this you need:

a craft cutter which works with Make the Cut and can accept accept arbitrary vector art.  I'm using a Cricut with updated firmware (before the lawsuit happened).  See this instructable for how that worked.

some sheets of type 6 plastic, aka shrink plastic or "Shrinky Dinks"

"make the cut" software, or similar

a crisp image of the gear you would like to replicate

an oven.  (I use a toaster oven dedicated to baking plastics like shrinky dinks and sculpey).

Real square gears :) They must be a bit different if you want to rotate them properly

My experience with shrink plastic was that it always curled up. Did you have any special trick to keep it flat? I'd basically given up on ever using it again, but after seeing this I might give it another try.

By the way, although I do still have the Cricut and working MTC software, I've upgraded to a KNK MAXX cutter which is a much more industrial quality machine.

Hmm. I had no idea what "type 6" plastic is. For anyone who is similarly perplexed, it appears to be a plastic called polystyrene.

Out of curiosity, do you know what the (pre-shrunk) thickness of the plastic you used is? What about the post-shrink thickness?
foobear (author)  JesusFreke4 years ago
Pre-shrunk the thickness is about the same as a sheet of typical bond paper, maybe a little tiny bit thicker. After shrinking it is quite a good deal thicker, at least 4 or 5 times thicker.

With my imprecise plastic calipers it looks like It goes from about a tenth of a millimeter to about 2 millimeters thick.

Thanks for the info! I might have to find me some :D

your "biscuit" looks like a cheez-it! :D

great instructable, but it sucks to hear that make the cut wont work anymore, but how does the cricut deny the use of the program? sure the company does, but how does the machine know whether or not to allow the information to cut stuff be sent to it?
foobear (author)  zack2474 years ago
The software I bought before the lawsuit happened still works, but they're not allowed to sell it for the Cricut anymore.

It apparently works with other brands of cutters though. I don't know how or if they were able to specifically turn off support for the Cricut within the software.

Not only a nice idea for small custom gears, but this would also be helpful to the Steampunk people who need gears and what ever for their work too.

cool

This is a great idea. I have heard though that 'Make the Cut' no longer works with cricut machines. Any suggestions to alternatives?
foobear (author)  jonesy434 years ago
Oh man, thanks for letting me know. I just now read about the lawsuit. So... I guess people won't be able to do this instructable.

Probably a smart competitor will arise before too long.

Too bad.
