Made this for a very special friend for Christmas, read more about it here: http://samsskunkworks.com/#/portal-gun/

Thanks Kirby for the awesome design. Use PLA because of it's crispness and lack of deformation/shrinkage. Achieve incredible gloss finish using XTC-3D. Made vinyl cutouts on a Cricut machine and embedded them on the resin. For the light I used a couple of old color LED lights from IKEA and a polarizing filter from an old LCD screen to cover and diffuse. Super simple circuit, used a resistor to tone down the green so I git a richer orange.

This was a 3D print I could not pass up. Portal is a big favorite of mine and this model is really well done. I did modify the claw arms to attach with screws at the hinges to be a bit more robust. Chopped up an old audio extension cable for the wires and used plastic from a clear soda bottle for the outer cylinder. I decided it needed a proper display stand after I made it, so I grabbed some references from the games and modeled and printed my own version of the in-game stand to display it on.

Trigger causes color change via LED strip & Sparkfun Redboard.

I decided to go to a Halloween Party as a player from Portal. Added the electronics based around an Ardiuino Pro Mini, with MP3 sound board. Used an addressable LED strip to add some animation to the portal firing. Logos printed in sticky back vinyl, added some weathering after sanding down the white bits to get rid of most of the layer lines. Put some silver paint around the edges to make it look like the black paint has worn down to bare metal underneath. Finished with a matt clear coat which finished it off perfectly.

Hey! After 2 years of work (but mostly waiting, because i didn’t have time) i finally finished it! It’s a really good model, but i don’t really like the handle, it’s not comfrotable

Still more work to do but its progressing nicely. I will have to do a lot of modification to get the speakers, LEDs and electronics in it.

Doing some modifications to the print to hold my custom electronics for sound and lights.

first big printed project!

After a very long time, I have finally completed the Portal Gun. Took a lot of sanding, painting, and patience but I finally made it. For those who are making this, the tiny pieces for the articulating arms break extremely easily no matter which way you print it, so I chose to omit them in my final design. Thank you Kirby Downey for creating this wonderful free file!
