Tern GSD / HSD 3D Printed Model and Christmas Ornament

I love our Tern GSD. We just crossed 2000 miles ridden over the last 15 months and can’t really imagine life without it. Part of the joy is customizing it as we go – everything from racks and seats to locks and Woom-holding aero bars. Even a clubhouse-mounted bubble fan that kinda worked! (Here’s a video)

I posted that video to the Tern GSD Facebook group and a Tern rep asked to use it in an upcoming promotion – why not! They kindly mailed me a wooden GSD model that was a blast to assemble.

I hoped to share the model with friends, but Tern doesn’t sell the wooden model – it’s a promo-only item. So I did what any reasonable person would do and scanned each piece, created digital model files, and 3D printed the entire thing in custom colors for all our friends with bikes 🙂

I experimented with printing loose pieces as well as carded/flat pieces in a custom frame to best emulate the pop-out-of-wood feeling like the original model. I don’t love the extra plastic created by the frame, so I’ve mostly printed loose versions and stuck them in a manila envelope with instructions and a color-coded keychain.

How can I get one?

• You can download the files for free on Printables (GSD / HSD). If you don’t have a 3D printer, check with your local library!
• I also have printed a few on-demand for people from Etsy (GSD / HSD)
• You can download the Christmas tree ornament piece for both bikes at Printables.

Here are some filaments that I’ve found to be a good color match:
