Universal 3D Printable Portable Pull-Up System – No Hardware, No Limits

Take your fitness anywhere with the world’s first fully 3D printable, hardware-free, portable pull-up system designed for serious strength on the go. This innovative two-piece design mounts universally to any standard door frame without tools, screws, or damage—just print, place, and pull.

Engineered for extreme durability, each piece supports over 550 lbs and utilizes your body weight to lock securely in place. The intuitive form grips the door frame with mechanical leverage and friction, getting more stable the harder you pull.

Unlike traditional pull-up bars, this model features individual hand grips—one per hand—giving you full freedom to vary your grip position for targeting different muscles. Whether you prefer wide-grip, neutral, or close-grip pull-ups, you’re in control.

Key Features:

• ✅ Fully 3D Printable – No metal, no screws, no compromise. Print at home or on the go.
• ✅ Universal Fit – Mounts to virtually any door frame, no tools required.
• ✅ Ultra-Strong – Designed to hold 550+ lbs of dynamic weight.
• ✅ Modular Two-Piece Design – Train with full range of hand positions.
• ✅ Travel Friendly – Lightweight, compact, and easy to pack.
• ✅ Zero Damage Install – Leaves no marks or dents on your door frame.

Whether you’re in a hotel room, dorm, apartment, or your home gym, this compact powerhouse is the ultimate pull-up solution for modern nomads and dedicated athletes alike.

Print strong. Pull hard. Train anywhere.

How To Use:

1. Simply mount the protruding lip of the device to rest on top of the door frame
2. Apply weight to ensure no slippage and to test for a stable frame (ensure the frame will hold user's weight)
3. Enjoy fitness on the go!
