Plumer's Helper Boomshot from Mario + Rabbids

Tell us the story of your project: 

I wanted to participate in the Maker Faire cosplay prop contest. So as soon as I recieved the email I started taking screenshot of the gun in game so that I can use them as reference images later.

I then spent a few days modeling this in Fusion 360. 

Final 3D model from Fusion 360.

I printed all the parts, glued the subassemblies together and started to sand, prime, sand and paint the pieces.

I then painted it using an airbrush and added some cut adhesive vinyl for details.

 

How-to: 

I started by taking screenshots with my phone of the gun in Game. I used the folowing images

I then used fusion 360 to model this in 3d and was able to produce this 3d model

I modeled it as close as I could and took some liberties as not every aspect could be seen from the screengrabs.

I then started the long process of printing all the parts, 28 in total. It was approx 150 hours of printing.

Some of the first parts printed.

 

To save time while I was still printing some pieces i continues the process on others.

The next steps is glueing some of the parts together.

In this part I also added wood putty to fill in the gaps. Unfortunately I also found out later wood putty is horrible for wet sanding as the putty will dissolve in water even after its fully dry.

I covered the parts in XTC3D a product by smoothon to help in covering print lines.

It makes then shiny and smooth but not perfectly even.

 

I then sanded the parts with 220 grit and then 400 grit and applied primer.

First parts painted

Almost Complete

Updated picture after some glueups, Clear Coat, and some vinyl decals.

I used my older DaVinci Pro fitted with a laser attachment to cut the vinyl.

At this point I realised the back cover of the middle body was modeled incorrectly so I wen back to 3D modeling that part, printing, covered in XTC3D, sanded, primed, sanded again, painted, and clear coat.

Here is the completed prop.

Teaser: 
This is one of MarioRabbid's boomshot weapons in the game.
Aha! moment: 
Airbrushing is SOOOO much better than spray paint. In my opinion.
Uh-oh! moment: 
Finding out wood filler putty is water soluble even when it is dry.So it is no good for wet sanding as it will just dissolve away when the water touches it.
