Description

Not a functional gun. Bears only a resemble to any real firearm. Internals and measurements do not match an actual firearm. Can not be fired.

Update: Display stand available here

My version of the Auto 9 Pistol from the 1987 movie Robocop. It is based on photos of the screen used props and references images of the base gun.

The model is divided into logical parts and does not require glue for assembly though glue will help for strength in some places. This allows for easier prep for sanding and painting. Real hardware such as screws and springs is needed for assembly.

Assembly is mostly straight forward. The slide must installed before the barrel. The barrel base is place into the main frame from top and the rear barrel then slides into it. The barrel surround is then installed to hold the rear barrel in place with the front barrel and joiner pieces installed in the front of the barrel surround.

The trickiest part of the build is the magazine release which requires all debris to be cleared from it's path. Also it needs to be held in place with the grip. So they must be installed one after the other.

I will work on a detailed assembly video but wanted to release the files now since they are finished enough for release.

Assembly Video:

Hardware Required:

3 - M3 x 4mm Socket Head Bolts (Bottom detail of Barrel surround and rear sight)

3 - M2 x 6mm Socket Head Bolts (Sight Rail)

1 - M5 x 16mm Socket Head Bolt (Secures barrel surround onto main frame)

4 - M4 x 4mm Pan Head Bolts (Secures grip to main frame)

2 - 5mm x 30mm Springs (Hammer and Magazine Release)

1 - 6mm x 30mm Spring (Trigger)

Recoil Spring

1 - 12mmx60mm Spring OR 2 - 12mmx35mm springs OR 3 - 6mmx30mm springs

All will work. 6mm spring will be the cheapest option but won't be as strong as a 12mm spring. I found 35mm springs quite easily on Amazon.

I made this for my husband. The model is very well done, especially for a free model. I had no issues with printing or slicer settings. I had a few problems with assembly: 1) the mag release spring was too tight and I could not get the grip to screw in all the way. I ended up not using that spring. 2) I watched the assembly video multiple times and I think a step was missed, but there is a gap on my weapon that is not on the video, and there was an extra piece that was not shown in he video, and the piece that was shown in the video was not in the files. but overall a great build, please make more 🤗

Printed without problems on X1C with a generic PLA Tough Black and generic PLA Silver. Very nice model. Very easy and satisfying assembly. Next step printing the stand and sanding eventually some parts :)

VERY NICE build sir. can’t wait to assemble it. by the way, I’m a bit confused about the wire gauge of the springs… I bought springs but they are way too strong.. I found all the great sizes but there are so many wire gauge specs that I’m a bit confused… would you kind enough, please, to let me know the wires gauges you used ? Thank you ! Fred

@Neebick

I designed it to use the common multi spring pack boxes that are available on Amazon and at Harbor Freight. Looks like the wire gauge is 0.5mm for the 6mm springs and 0.4mm for the 5mm springs. The slide can handle beefier springs. I used 2 35mmx12mm springs with a wire thickness of 1mm.

Replying to @Neebick :

you are amazing. thank you !!

This is exactly what I was looking for. Mechanically put together with working parts. I want to figure out how to make the slide lock. As a kid...Robocop blew me away when it came out. Is this to scale with the actual prop. It looks smaller...I haven't held it yet so that maybe just the way it seems on camera...

The designer has replied

@Neebick

I skipped a working slide lock since would be have been pretty fragile to get it accurate. The model was scaled to the Beretta 93R which is the base of the Auto 9. The 93r is a smaller pistol. They actually added the parts for the movie since they thought it looked too small in Robocops hands. I then scale images of screen used props to size the add on parts. The only part that may not be accurate is the magazine measurements since they were near impossible to find. Also, I am taller and have larger hands so that may throw off the scale as well.

Thanks for the rating. Always good to hear that a model worked well for others.

@ippo279

Fantastic design! Just curious, how long did it take you to design this from start to finish? Again, absolutely incredible design here!`

The designer has replied

@Neebick

Thanks. I appreciate it. This one took a while since it's based an actual gun and getting details right can be difficult. Took me about 2 months mostly due to the holidays. 2 weeks off and on collecting references and making base model. Another week refining details and double checking sources. Week working through how parts will fit together and adding tolerances. Couple weeks printing and fixing issues as they pop up. I made a series of impractically long videos on my Youtube of me making another model. That one took about 8 hours start to finish.
