Toy Exploding Grenade!

This one will definitely be a fan favorite with kids and adults! I wanted to create a grenade toy that exploded when it hit something. After a lot of thought, I decided to design it using magnets (16 in total).

I first created the grenade, and then I broke it into pieces like a puzzle. After that, I added the holes for the magnets, and now we have a functioning toy grenade! It is quite fun to use, and I'm excited for you to try it out! Keep in mind that it's very easy to lose the pieces because they go flying everywhere, but its worth it lol.

I made five files that make up the grenade. The bottom section, middle piece, top section, handle, and pin.

I didn't put all of them on the same build plate to make keeping track of the magnets direction (polarity) easier.

This model is for PERSONAL USE ONLY, if you want a commercial license and access to more awesome models you can get it on my patreon https://www.patreon.com/kevbot_3d

Print Setting:

I recommend printing the bottom pieces first, then moving to the middle piece, then the top pieces, followed by the handle and the pin. I will have 3MF files for each piece with all the settings I used to print them (including the stops needed to embed the magnets into the print).

I recommend 30% infill or less. If you do more infill, the magnets might not be strong enough to stick to each other.

You will need 16, 6 by 3mm Neodymium Magnets. These are the magnets I use if you are interested:

If you don't know how to orientate the magnets please message me and I will put a video together if needed.

You can also purchase key rings to attach to the pins here:

Scalability

I would not scale it up but you might be able to scale it down a little bit.

Supports Needed?

No

Thank you for the support! More designs are on the way and if this design is a hit, I will most likely make some variations.

Happy Printing!

Cheers,

Kevin
