Airplane construction toy

My first published model. All parts are optimitimized for 3d printing. All parts are printed without support or brim, except propeller. You will need supports for propeller, this part has too shallow slope (low pitch angle) and it is optimized to rotate by little wind blow.
 

Parts are easy to assemble and disassemble and offer great color personalization. Parts are also big, except for the wheels, so toy should be suitable for 3 years+.

No special instructions for slicing, I print all parts with defaults and use adaptive layer height. Check screenshot for orientation of selected parts, all other parts are oriented correctly.

I will update model with additional features and optimizations:

• Wheels needs more details
• Cabin needs more details
• Cabin “lock in place” optimization
• Undercarriage will be switchable with hydroplane attachment
• Undercarriage “lock in place” optimization
• Two bladed propeller
• Transformation to helicopter
