The Remanufactured Butterfly Project

Greetings!

I’m embarking on a project and I need your help.

As some of you may know, I’m a fan of both the Duncan Butterfly and 3D printing. I’ve recently found that I rather enjoy printing new halves for the metal axle found in Duncan Butterflies and Imperials. I haven’t found a way to source the axles other than buying new yo-yos, but I really like the new Butterflies, so I wouldn’t want to buy them just to harvest axles.

So I need you to send me your spares axles and your broken Butterflies and Imperials, so I can give them a second life.

I’m really interested in experimenting with this form, so I’m planning on producing a unique design for every axle.

Here’s my offer:

If you send me 2 or more Duncan axles or broken Butterflies or Imperials, I will send you back 1 unique metal fixed axle 3D printed plastic yoyo, free of any other charge, in the CONUS.

If you send me 1 axle and $5 (to cover my shipping), I will send you back 1 unique metal fixed axle 3D printed plastic yoyo in the CONUS

All extra axles will be used to make unique metal axle 3D printed plastic yo-yos for sale on this thread for $15.

Feel free to DM me any questions or offers. If you have a rather large lot of Duncan axles I’m willing to buy them from you.

These are my first two Remanufactured Butterflies, #0 (right) and #1 (left). These two are my personal ones and aren’t for sale but just to give you an idea. I have about 4 designs in the queue waiting for axles, and most of them start to stray pretty far from “Butterfly” in both shape and size :grin:

Are you printing in plastic or metal? The prototypes look like they’re plastic.

Plastic. The metal axles are from Duncan fixed axle yo-yos.

Looks great! I may have some axles, will have to search though. What’s the weight of the #1?

I don’t know that I’ve actually weighed #1. This one is incredibly similar to #0 which is 51g.

I was only planning to work on the fixed axles but if you didn’t want them I’d give them a try.

This is an awesome idea! I should have two axels, expect a dm from me soon
(Maybe not I’ll have to check :slight_smile: )

#2 is for sale. The halves are bell shaped, with the widest diameter above the rim. 53g, and should be around 57mm wide and just under 40mm wide. I will verify dimensions with calipers later. This Remanufactured Butterfly uses the American made Butterfly axle, which is basically just a straight metal dowel with textured ends and smoothed center.

@pyrotechnic might have some axles left over from mods.

Already sent my extras to him

Well I’ve already learned a valuable lesson in this project and it’s that there’s a ton of variance between Duncan axles and that I should re-measure each axle for each design.

Good to get a lesson like this in early :grin:

This is why I haven’t sent you an axle I have three different sized axles somehow lol. I assumed I had them from various throws but maybe they are all butterfly

Just means I have to measure twice :grin:

17

Butterfly XTs work? I have a few extras from when I’ve needed emergency string on the road.

18

For this project I’m focused on fixed axles. If you were sending fixed axles I would also take XTs but I don’t need XTs alone.

19

i probably have a bunch of axles you can use, i’ll dig around…
