If a “Benchy” could float… “Marky” could sink it.😏
I now present “Marky”, the benchmark biplane bomber!
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… AND it drops a bomb.

No Supports:
How?? This little guy is designed to be printed on his nose.
Fast:
PETG-HF = 54m 46s (compared to 43m 40s of standard 3DBenchy with identical settings)
PLA Basic = 41m 40s (compared to 30m 47s of standard 3DBenchy with identical settings)
Cheap:
PETG-HF = 15.09 g (compared to 11.39 g of standard 3DBenchy with identical settings)
PLA Basic = 15.31 g (compared to 11.55 g of standard 3DBenchy with identical settings)
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 four locations circled in yellow:
Geometric accuracy:
Wing span = 55mm
Wing spacing = 26.27mm
Wing support thickness = 2mm (Qty 4)
Tail rudder thickness = 2mm
Wheel diameter (front wheels) = 14.6mm
Wheel runout (front wheels) = How droopy are the first few layers on the front wheels?
Tail width = 27mm
Nose diameter = 24mm
Nose to tail (Z-height accuracy) = 56.5mm (nose to flat on tail)
Clearance test #1:
Marky's belly bomb is flex-fit and print-in-place; if your printer is dialed in, the bomb is droppable.😎
(also available without the removeable bomb… you know, for toddlers.)
Clearance test #2:
Good luck! Worked great on my X1C.👍
I actually intend for this bit to droop a bit so the pilot has a chin:
Extra Feature:
Eyelet feature (yes, it is positioned directly above the center of gravity) to hang your Markies from… everything?
Hang Marky from your monitor, rearview mirror, shelves, showerhead, nose ring… whatever floats your tugboat.😏
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…
