Portable Concept 2 Rowing Machine Smartphone Cradle

thingiverse

Rowing on a machine can be a real snooze-fest, but I've found that catching up on a suspenseful movie or TV show makes the time fly by and really helps me hit my cardio goals. Unfortunately, most gyms don't have TVs, and those Concept 2 PM4 rowing machines just aren't designed with phone holders, so I'm stuck scrolling through my screen while trying to get in shape. That's why I created this portable smartphone cradle - it clips together easily and lets you enjoy your favorite shows or music during your rowing session. It was specifically designed for an iPhone 8 and a Concept 2 PM4, but any phone that's about 67mm wide will fit just fine (if you need the Fusion 360 files, they're attached). You can probably use it with other Concept 2 models too. I recommend printing this cradle out of durable plastic like PETG - it's flexible enough to withstand a few bumps and bruises.
