Four cameras, four tripod holders, one training session: phone and tablet editions side by side.
We designed this holder for people who find small screws, clips and spring clamps hard to use, including people with arthritis, weak grip, tremor or limited finger movement. Every part of the design choice below removes one more thing your fingers have to do.
Tighten and release with the whole hand pressed against the knob, no pinch grip or fine finger control needed at any point.
65mm across with 12 rounded scallops, easy to find and turn even with gloves on or limited dexterity.
A coarse 2.5mm-per-turn thread means a few turns, not dozens, to go from loose to locked.
Interlocking teeth carry the load once they're meshed, so you only need to tighten it snug, not crank it down with force.
A new locking position every 2.5mm along the arm, so your phone or tablet lands exactly where you left it last time.
Three printed parts. No nuts, screws or springs to drop, lose or fumble with cold or shaky hands.
Most phone holders use friction: a smooth surface squeezed tight and hoping it stays put. This one uses 11 interlocking teeth, 2.5mm apart, locked together inside the head: your phone or tablet is held in place by the shape of the parts, not just by grip strength.
Both editions share the same head and palm knob, only the arm length changes.

Video Replay turns your phone, tablet or PC into a multi-camera instant-replay system: watch yourself train seconds after you move, from several angles at once. It's built for darts, golf, boxing, cricket and any technique-based sport, and it works completely offline: no AI, no cloud upload, no account needed. Your video stays on your own device unless you choose to share it.
Whatever your age, your ability or your sport, getting better is personal. Video Replay is built for your own improvement, measured against no one but yourself. But before you can review your technique, you have to actually get your phone or tablet mounted and filming, and for anyone who finds small screws, clips or spring clamps hard to manage, that first step can be the hardest part of the whole session.
This tripod holder removes that barrier. It was designed and created by 3D Origins as a free companion accessory for filming with Video Replay, specifically so a stiff thumb, a tremor or a weak grip is never the reason someone can't record their own training. Sport, and self-improvement, really is for everyone, and this is one small part of making that true.

A 3D printer with a 0.4mm nozzle (designed and tested on a Bambu Lab X1 Carbon or P2S), PLA or PETG-HF filament, and the free print files from MakerWorld. Full settings are in the spec sheet PDF at the top of this page.
Yes, there are two editions sharing the same head and palm knob: a 246mm arm for phones, and a 297mm arm for tablets like the iPad.
That's exactly what it was designed for. It's tightened by pressing the flat of your palm against a large 65mm knob, not by pinching with your fingers, and it needs only a few turns rather than dozens. There are no small screws, clips or spring clamps to fumble.
We're working through the Amazon store listing process now. Until then, the model is free to print yourself via MakerWorld.
