Canadair CL-415 | Bombardier 415 Super Scooper | Display Model Multi Color

The Canadair CL-415, formerly Bombardier 415, is a specialized firefighting aircraft renowned for its efficiency and reliability. Designed to scoop water from lakes or rivers, it plays a vital role in combating wildfires worldwide.
In my opinion one of the most beautiful airplanes which is why I wanted to own it as a display model!

I've uploaded the model in two different sizes:
- 100% = 456mm wingspan, 316mm long and 133mm high (1:63)
- 125% = 568mm wingspan, 395mm long and 167mm high (1:50)

Build volume:
For the smaller 100% size a height of 208mm is required, for 125% size 260mm.
The plane should be easily scalable to at least 150% without the tolerances becoming too large for problem-free assembly.
Scaling it smaller than 100% requires a very carefully adjusted filament.
The clearance applied at 100% is 0.2mm.

Besides some single color parts, the main components are printed with 4 to 5 colors (depending on whether you want to use the same color for the walkways on the top of the plane as for the windows).
The individual parts are glued together. The propellers are glued to the shaft and the tip and then clipped into the turboprop engine and are rotatable. 
When designing, I made sure that all parts can be printed in their optimum orientation. They are already correctly aligned for printing.

Apart from the RED_Vertical-Fin part, no supports are required. I have uploaded this part in two versions. With built-in support structure and without.
There are different versions of the stand. Straight, tilted upwards and tilted downwards, as well as mirrored versions of the latter.
 

Print instruction:
I've refrained from uploading all multicolor components individually for a better overview. Open the files in the slicer and divide the model into parts, not objects! You can then assign the corresponding colors to the parts.
I've uploaded a version of the large wings which are connected with two small bridges. This should make the print a little less wobbly, even though printing without these bridges had no negative effect on the print quality for me.

The following colors are needed:

• yellow → I recommend a warm shade of yellow. In the photos, I used Pineapple Yellow from Prusament (too light) and Melon Yellow from Fillamentum (slightly too dark).
• Red
• black
• silver
• opt. gray → For the walkways. Not absolutely necessary, just to create a contrast to the windows.

The best way to compare filament colors is at filamentcolors.xyz.

The yellow is needed the most, the large version with 2 perimeters and 15% infill should not require more than 400g depending on the purge volume.
2 perimeters and 10% infill are sufficient. I printed the 100% model with a layer height of 0.2mm, the 125% model with 0.22mm.

The exhaust of the turboproengine is glued on, so the part can be printed with a simple color change and without purgetower, as long as it is not printed together with other parts.

Assembling the propeller is probably the trickiest part. First glue the shaft into the tip and make sure that the holes for the propellers are aligned correctly. As long as the glue is still wet, you can use a propeller to ensure correct alignment. The propellers are placed with the curvature facing backwards, as shown in the photo.
