This is a full-scale replica of the M-77 Paladin heavy pistol from Mass Effect. Save yourself 200,000 credits and print one for free!


I printed all of the parts at 0.2 mm layer height. In addition to the printed parts you will need super glue, a paperclip, and 3 rubber bands. The paperclip is used as an axle for the trigger and the rubber bands are used to apply tension to the trigger and slider mechanisms

Most parts include built in supports with the exception of the "grip_front.stl" which requires supports.

It has a slider because I was originally planning add internals from a NERF gun to it. I might upload a non-hollow version with the slider joined to the rest of the body sometime.

Looks like Slider_part2 should be two separate pieces, since in the pics the very end of the slider (the tube) is white.

I changed the filament mid-print to achieve two colors on a single piece.

Ok, thanks.

Did you paint the black around the circles?

Nah, I printed little black rings and glued them in. You could probably paint them in just as well if you are careful.

Do you still have the rings? Those would be great to have!

I uploaded a part called "black_ring" which should work.


Could someone please list the parts with what color they should be printed in? That would be very helpful.

Most of the parts should be printed in white. The parts that should be printed in other colors are grouped together with the color indicated in the filename.

Thanks, I guess I should have looked closer at the files.

Now that I looked, I actually didn't indicate the colors for all of the pieces that I should have. The "barrels", "handle_edited", "slider", and "frontpiece" parts should all be printed in black.


I've had a problem understanding how the other piece in the main file should go (not the trigger or main body). I hope you could help me.

It slots into a groove in the top of the main piece (which you will notice when the two halves are together) and holds the pieces together.

Thanks! It is a really smart design, good job!

Can I ask for a favor, I am currently printing this and met an obstacle on the way. The main piece doesn't fit on my print bed. If you could do me a favor, can you cut the main piece into smaller parts please?

I've split the main piece into 6 separate parts (3 for each side) and uploaded them. It's up to you to figure out how to attach them together.

i'm glad to say that it's incridible !

a question :

"frontpiece" have floatings parts, how i deal with then ? print with support ? do not use the floating parts ?

The floating parts are supports that I manually added to the model and should be removed after printing. If you want you can remove them and add your own supports (either manually or through your slicer software)

First of all let me say this is really well done. I've starting printing but I noticed there is no "M" sticker in the black sticker file? Unless I missed it somewhere?

You are right. Thanks for catching that. I will re-upload the file with the missing parts. EDIT: The new file has been uploaded.

I'm having fun trying to figure this build out. The trapezoid support inside of the main body of the gun was near impossible to get out (I had to chisel it out with a flathead screwdriver and a hammer) and some pieces have ended up needing a few manual supports. I've figured out most of the fit, and the sliding mechanism, but I can't figure out where to attach the trigger (using a rubber band, I see the paper clip axle) where it will have tension. If you could post a quick guide on that I'd really appreciate it.

Loop a rubber band through the larger hole in the trigger and attach it to the hook on the inside of the main part of the gun (see photo in the gallery for reference)

Really nice finish on that mate, well done.

In the process of printing this right now. I had to splice the main piece in half since it was too big for my printer. We'll see how everything comes out by the end of the week!

How did you slice it in two? And can you send me the files?

Can either you, or the OP post a split version of the main piece? I too cannot fit it onto my build plate, but I've had trouble getting the model to split cleanly.

You can use netfab to split the file

Do you happen to have a tutorial on how to rig up the trigger and slider to the rubber bands?

I really love this model. I have a couple questions hoping you could answer them. I have been having some trouble with your added supports as they seem to be "sagging" in the middle b/c they are just hollow shells. Is there anyway to get all of these model parts or even just the .stl without support? Otherwise this looks great and I can't wait to get it all printed!

I've uploaded alternate versions of the body and handle pieces without supports.

Having worked on a Carnifex/Paladin myself, I realize how much work the geometry for this model is, and there are a lot of small details. You've gone much further into detail and made it much better than how I went about it, I'm very impressed.
