The Cycloid Drive 25:1: a 3D-printed NEMA17 gearbox, measured on our bench. Free parts list, files $7.99.See the parts list
Photo turntable / HS-MEC-006 / coming soon

Click-Stop Turntable

Turn the knob, not the platter. Every click turns your object exactly one twenty-fourth of the way round and holds it there, so 24 photos make a clean 360° spin. Three printed parts, no hardware.

01 / How it works

Click, photo, click.

The platter is one big printed gear. A small gear under the knob turns it four times slower, so one turn of the knob is a quarter turn of the platter.

Under the platter, a springy arm printed into the base drops into 24 little dips, one every 15°, and holds each stop. Take a photo, click, take a photo. After 24 clicks you are back where you started.

That gives you even steps for a smooth 360° spin video, or a full set of photos for a 3D scan.

02 / Specs

04 / Questions

Good questions.

Something else? Email help@harbeworks.com.

What is it for?

Product photos, 360° spin videos and photo-based 3D scanning (photogrammetry): anything where you want the same small step between photos.

Does it need a motor or batteries?

No. You turn the knob by hand and the clicks do the measuring.

How heavy can the object be?

It is designed for objects up to about 500 g. That is a calculated figure: we have not load-tested it yet.

Will it fit my printer?

The base is 191 × 154 mm, so you need a bed of at least about 195 × 160 mm (Bambu A1, P1, X1 and similar).

When can I get it?

Soon. The files are finished and checked in CAD, but we have not printed this one yet. Follow @harryson.stl for the launch.

Files or a printed one?

Both are planned: a digital file pack for your own printer, and a printed, assembled turntable.

The drive on the platter.

The gearbox in the size render is our Cycloid Drive 25:1. Its print files are available today.
