The D

The WAVE ARCADE D fin is designed for down the line drive for mid-sized longboards & hybrids. Give your board some of that old style, yeah?

Give your mid-sized single fin longboard or hybrid some of that old school feel. This surf fin is designed for down the line drive and stability to give your surfboard that old school log feel.

This won’t be the best fin for drawn out carves or turns, but will allow you to cruise down the line with mad style. The base on the D fin is flipped so you can position it as far back in the fin box as possible.

D Fin Specs:

  • Base: 160 mm (6.2 in)
  • Depth: 176 mm (7 in)
  • Foil: 50/50 symmetrical
  • Sweep: Small
  • Base designed for US Box.

If you plan to 3D print this fin, make sure your printer has a build area of at least 8 in x 8 in x 8 in (203 x 203 x 203 mm).

Enjoy! And please let us know how it goes.

How to Make this Surfboard Fin

Making your own fin is easy! With this WAVE ARCADE 3D-modeled fin you’ll need to:

  1. Download the .STL file from the email you receive or your account page after purchase.
  2. Open the file in your 3D printer’s editor to modify the print settings and convert it to g-code
    • This is where you’ll determine the print orientation, infill patter, and print speed.
  3. Determine the filament material you’ll print with.
  4. Send your file to the 3D printer and press print!

You can also use this file with a CNC machine or as a guide to cutting and foiling your own surf fins by hand.

Be sure to check your measurements & settings. Get in touch if you run into any problems!

3D Modeled Surf Fins

Welcome to the future. With the advent of accessible 3D printing, the possibilities for surf fin experimentation are not only endless, but totally feasible.

By purchasing one of our 3D modeled surf fins, you’re acting as an early investor in the WAVE ARCADE project. You’re helping us ramp up production, testing, and ideation aimed to keep surfing as fun and as sustainable as possible. We aim to improve the oceans & beaches and have a great time doing it.

Be aware that not all 3D modeled surf fins currently available have been tested or printed. Also note that the production material and production settings you choose will have a big effect on the performance of your fin. If you find a problem with the file itself (layout, dimensions, etc.), please get in touch and we’ll help you solve the issue.


This surf fin is available as a digital file for you to experiment with production methods of your own. Simply download the .STL file, load it up to a 3D printer program, confirm the dimension (alter them if you’d like), and print.

WAVE ARCADE digital files are for the true experimenters and for those who can’t wait for WAVE ARCADE to get its act together and offer physical products.

We encourage you to find new, creative, and sustainable methods and materials to produce our digital products.

With every digital product purchase, you’re bringing us closer to funding an operation that allows us to ramp up testing, production, and sale of WAVE ARCADE physical products.

Thanks for the support! Go ahead, go shred.
