“Bobbing Bobby” buzzes “Benchy” while briskly bouncing between bushes, bobbling beside babbling brooks, boldly bypassing big boulders, & bravely battling brisk breezes. 

I now present “Bobbing Bobby”, the Buoyant Benchmark Puddle-jumper Benchy Buzzer!

Bobby may not be a fighter jet… but he's got aggressive overhangs and gnarly bridge testing!!

Spinning Propeller:

• I recommend carefully cutting around the base of the propeller top pop it loose rather than twisting.

No Supports:

• How?? This little guy is designed to be printed on his nose.

Part-Cooling Performance and Overhang Capability are tested by these (see image below) highlighted features:

Bed adhesion is tested by having minimal surface in contact with the build plate:

• SERIOUSLY. You might want to consider using a build plate adhesive; cause you're about to find out how reliable your first layer stick is!
  • Bed adhesion is arguably the most important component of 3D printing; that's why it's included in this benchmark test.
  • If you just want the plane, feel free to add a raft, brim, or recess the plane into the build plate a little to give yourself a larger starting surface area.👍

  • 

Bridging quality is tested in the locations indicated:

Geometric accuracy:

• A = 76.2mm
• B = 19mm
• C = 67mm 
• D = 14.8mm
• E = 12.75mm
• F = 22mm
• G = 2mm
• H = 1.5mm
•  J = 2mm (yes, “i” is skipped intentionally)
• L = 2.5mm

Note: Measurable dimensions are the same as the original “Bobby”.

Improvements Made:

• Added drain holes to bottom of fuselage.
• Added ballast to pontoons.

The beloved 3DBenchy has a special place in all our hearts. Why? It's cute, it's quick, it's useful, it's repeatable, it's comparable, it's measurable; and it will always WOW a toddler and grandparents alike. Thank you, Daniel Norée, for creating the 3DBenchy which we've all come to love; but alas, even legends fade.

I think it's time we consider another contestant who's a little younger than ye olde tugboat…

As always, feedback is welcome! 

ENJOY!
