It all started with the game. I'm not a massive fan of FPS, but my boyfriend convinced me to give Portal 2 a try. I think i'll trust his game recommendations a little more from now on, because I loved it!…which based on my 'logical' progression of thought then leads on to “I have to make it!”. And so it began.
The research began with the one and only Volpin. Harrison Krix is a real prop maker, and his ASHPD's are a treat for the eyes! Check him out at https://www.instructables.com/member/volpin/  and his blog at http://volpinprops.blogspot.com/
Needless to say, with neither the tools, nor the talent, I didn't expect to end up with a prop which could be put alongside his and look the part. So without the tools, how could we make a decent replica of everyone's favourite ASHPD?

I've uploaded this Instructable for theHurricane Lasers comp; think of all the awesome costume and prop parts that could be made with a laser cutter! Or maybe even the stand for this ASHPD which I have the acrylic for, but have neglected to complete due to being distracted by new projects. :)

This isn't a list of all the parts needed, rather a run through of the build.
Please feel free to ask any questions; i've gained so much from this community, now i'm just glad to be able to share something in return!

You can see the cosplay skit I used this prop in (which won best skit!) on YouTube here.
You can get the 3D printed parts from Jarly Props on Shapeways should you wish to use the same ones as me.

Step 1: Where Did the Model Come From?

I'm not a 3D modeler…but my boyfriend Justin is! ( @_R3D_M0NK3Y on Twitter!)
After having a poke around online, I found a few models which were okay…but none that screamed at me “I am the most accurate ASHPD model you'll ever see!”. (my last poll I asked 'What is the most important thing about a cosplay costume' – 80% said accuracy vs 20% who said being comfortable!) Since accuracy was the goal, it looked like this had to be done from scratch.

The starting point was a rip using 3D Ripper DX. The original plan was to look through a portal at the player, which resulted in the rip pulling what is being shown through the portal as it is actual 3D geometry, not just an image. (when you see yourself through a portal, you're seeing another incarnation of the Chell model, so with the portals in the right layout you could end up ripping 3 or more copies of Chell!) Unfortunately, while it was whole, the rip was so low poly it was next to useless.
The best is what you can see in the picture I've attached; it is incomplete because it is is actually what the player always sees in the bottom right of the screen, and therefore for efficiency, it didn't need to be whole! It was however the best base to work from.
<p>i dont have a 3D printer so could i buy a portal gun or the parts from someone</p>
<p>try your local makerspace, memberships arent too expensive and they usually have 3d printers. </p>
<p>wow i need to make this!</p>
<p>Where can we download the model file? or can you upload it, please?</p><p>Thanks</p>
<p>Can you upload the files please ? I have a 3d printer and it will be usefull for other people (sorry if i made mistake)</p>
Can you please upload the files now?:D I have a 3d printer and don't want to pay for shape ways ;-;
Awesome work <br> <br>do you have any dimensions or drawings with dimensions? <br>Id like to draw this on solidworks <br> <br>please send to risico96@gmail.com <br>Thanks
epic describes this instructable very well
you should put the models on this so that we can find somewhere else to get them made, and for a cheaper price.
This is not good, it's superb! amazing job on the details and all else!
really cool!
Congratulations on being a finalist in the Halloween contest!!! Can&rsquo;t wait to see if you win! Good luck!
So which material did you choose? And what was the total cost?
Please tell!
That is just fantastic, I love it, awesome. :)
Simply amazing
Can we get the 3D model anywhere? I have access to a 3D printer (hooray for hackerspaces) and there's no way I'm paying a couple hundred bucks on shapeways.
3D printing is awesome... but expensive... awesome work and all but no money to do this kinda project... i'll keep it in my fav for future use :D Thank you for the awesome instructable!!
This makes me so happy! :-)
Me too...don't you worry! :)
Epic! Just an awesome prop build. <br> <br>If you need help getting the sound board working let me know- me make circuits too. :) <br> <br>Didn't I see this build on the RPF a while back?
Haha awesome! I'll be in touch for sure!<br>And yes you did; I dropped off when they got hacked and really need to get back to it...
This is amazing! Spot on!
Thank you so much! :)
That is absolutely stunning. Probably the best one I've ever seen. Great job. :D
Thank you! I'm really proud of it. :)
