Despicable Me 2 - The Jelly Gun

[Daniel Nelms]

So I have been working off an on to designing Gru's Jelly gun from Despicable me 2. This is an on going project so I will post updates here.

Attached here is a screenshot of how it is looking so far.



I am designing it to be 3D printable, I think I can make it look pretty spot on with a good paint job when it's all done. It still needs a lot of work but it's a start.



One thing I am stuck on is where to find the glass jars. They aren't standard mason jars, if you look close you'll see that they aren't round but in a hexagon knind of pattern. If anyone knows where I could find such a jar let me know.

I plan on making the "jelly" by using water absorbing polymer beads and a mix of food coloring, I might also but in a small LED to really set off the look of the "jelly".

I think I can chrome up that parts that need it and use a dark metallic spray paint on the rest, shine, and buff it out.

Let me know what you think! I don't believe anybody has done this yet.

very interesting and make it so .
Great movie and an interesting project. I will be following this build :cool

A quick Google search will get you hexagonal glass jars.

Awesome!!! Right now I'm working on the Fart Gun for Halloween. I thought about building this, but the Fart Gun is just so iconic. Awesome movies, I'm hoping for Despicable Me 3.

Yeah I guess hexagon is the wrong word, maybe octagon looks more like the picture? I found this here http://www.sciplus.com/p/10-OZ-OCTAGON-GLASS-BOTTLES_54588

The fart gun should be cool! I saw a little toy one at target yesterday

My plan is to make two of these, one for each of my daughters. My hope is I can paint and polish all the parts to look metallic just like in the movie. I'll post pictures as I go for everybody to see.

Just a quick update I have molded and cast the cone nozzle in resin.

It's starting to take shape...

 

[OldSkoolEffects]

May I ask why you printed the tube parts? Wouldn't it be far easier to use tubing of the correct dimensions and design the printed parts to fit it?

 

[Daniel Nelms]

Just because it was easier for me to scale it in software to get it exactly how I wanted it, Im doing all the finishing work and making molds as I go so I can make resin copies.

The jelly jars look similar to some of my drinking glasses. Try searching "working glasses with lids"

 

[Daniel Nelms]

Yeah I found some that look pretty good, I'll snap a picture on Monday.

Making a mold of the main shaft.

 

[Daniel Nelms]

That's the jar I ended up finding. I haven't built the jar mount yet so I just sat it on top so you could get an idea of what it looks like. It's filled with water absorbing polymer beads, water, and purple food coloring.

I made a cast of the main shaft

 

[vidman]

AWESOME progress, it's looking more and more like the 1 in the flik

 

[Daniel Nelms]

I made a mold and cold cast the grip/trigger/and mechanism part as one piece.

 

[Daniel Nelms]

It's been awhile since I updated the thread but I have been a busy little bee! It's almost complete and I made molds out of all my original 3d printed parts.
It's just missing a few more greeblies which I painted this morning and are out back drying. This one here is resin cast, and finished just in time for Halloween as my daughter is going as a minion. I'll post more pictures soon and will likely do a limited run if anybody is interested.

 

[vidman]

that has come out very nice, congrats, enjoy the 31st

 

[Daniel Nelms]

Here are more pictures after adding the other greeblies.

I added a bright red barrel plug which is removable because my daughter will be carrying this around while in costume as a minion and I want to make sure that nobody would for any reason mistake this for a real firearm (yes theres plenty of stupid to go around).

If you want one of these for yourself check out my run here.
