Hi, I'm designing these 3D models in my free time (it's just my hobby), always providing all of my designs for free here on Makerworld. Often prototyping requires a lot of material, so if you like my work, consider supporting me for free by dropping a boost. =) But whatever you decide, enjoy the models and happy printing! :) - Oli
🏋️GymBuddy: The Ultimate Gym Timer
Are you spending more time scrolling through your phone than lifting weights at the gym? That was me. I’d sit down for a quick break between sets, grab my phone, and suddenly realize I’d taken a 5-minute break instead of 60 seconds. It was distracting, unproductive, and ultimately frustrating. 💡
That’s why I created GymBuddy: a simple, distraction-free device to keep me focused during workouts. It’s a compact gym timer that reminds you when it’s time to get back to work.
💪 How It Works
- Distraction-Free Timer: Displays elapsed workout time in the format HH:MM, so you can track your session without needing your phone.
- Break Timer: Press the button to start a 60-second break timer.
- Buzzer Reminder: A buzzer sounds when the 60 seconds are up, letting you know it’s time to get back to your set.
- Smart Button Control: Press the button again to stop the break timer and silence the buzzer.
