Creating an attachable stencil attachment for a spray can.

Graffiti however cool it may be, is frowned upon by the man, so if you do decided to display your artwork publicly or spruce up the boring neighborhood you should do it in a way that's easy, quick, and simple. That's where my invention comes into play.

Step 1: Welcome

Picture of Welcome
Welcome to the brand new world of 3d printed stencils.
     By printing your stencils via a 3d printing service instead of cutting them out laboriously like some dolt, you can have razor sharp edges and a wide range of designs. Plus the stencils you produce will be strong, sturdy and dam impressive.     

What the spray can stencil attachment will allow is for you to take your artwork to a whole new level, via 3d printing and a free modeling program called blender.

Step 2: Doubletake

If you haven't looked at my other instructables yet, I urge you to do so because you'll find many links explaining how to use blender.

I've attached a model of a simple spray can if you would like to follow along.

It will allow you to make your own design that you can get printed if you'd like, because the concept is fairly simple.

Step 3: Steps

I've taken a few screenshots of the modeling process.

Basically what you need to do is to create a frame that can support the stencil.

You can either copy what I did, or make it your own.

Step 4: The Stencil

Next you will be needing a stencil that you want to make.

I have chosen this an image of Gir as mine.

You can do one of two things.

Either you can put it as a background image, or apply it as a texture, (sizing is required). Either way should work fine, because you should be working with a singular plane that's highly subdivided, so you can easily extrude it to the desired thickness later, which happens in this case to be .1cm.

You need to make the areas where the paint will pass void of material, this can be accomplished by moving vertices and deleting edges. If you have any questions feel free to ask.

do you have any pictures of how they spray? could you explain more about the process of turning the imported image into the stencil? thanks!!
Sorry, but lemonie's right, this won't work. Most of the paint will be wasted and what does get through the stencil will barely apply a haze of color to the target.

For stealth stencils, people have often cut stencils out of a stiff material and then attached those to grocery bags with the bottoms cut out. Pizza boxes also work really well. Both options let you hide the can as an extra bonus.

The most important aspect is something that isn't even tangible: acting like you're supposed to be doing it. Put on white coveralls and just go to it.

This isn't going to work.

> You'll have most of the paint on the stencil, which will drip.

>most of the gas-force will be on the stencil so your range will be limited.

> If you've ever used stencils you would have found that the paint tends to spread-out and get fuzzy unless the stencil is pressed right-up to the wall.

- You'd get a small puddle on the ground and a fuzzy-drippy image on the wall.

You can get mist caps which might work a bit better. L is kind of right though, The optimum distance for low-pressure stencils is about a a foot.

Just a note, using those Postal stickers for tagging is a felony. Use decal paper.

Lets see a picture of the final painting!

This will work, but only if you press the stencil against the surface you're trying to tag.

It should still work if there's a slight gap, though not as well if there was no gap at all. This design wont allow for flush contact though I don't see why someone couldn't redesign it to eliminate the gap that's caused by bracket that holds the stencil.

Cool Idea, Do you have any shots of the final product? or Any pictures of the quality of the finished stencil?
The Cartographer (author)  Alphonsus1 year ago
Not yet, I figured that by the time it would be printed the contest would be over.

If you have a question about the process ask away.
