Description
A pair of involute spur gears for cutting from plywood or acrylic: you set the module, number of teeth, pressure angle and backlash, and the centre distance and mesh phase are calculated automatically. The gears sit on a base plate with two holes for axles (pins, screws). Lightening holes can be added.

What it is used for
Designs with complex geometry – bending panels, rounded shapes and living hinges – show what laser cutting can do and suit refined gift and display packaging.
Dimensions and parameters
| Parameter | Range | Default |
|---|---|---|
| Module | 1.5–8 mm | 4 mm |
| Teeth on the first gear | 8–80 | 16 |
| Teeth on the second gear (0 = single gear) | 0–120 | 32 |
| Pressure angle | 14.5–25 ° | 20 ° |
| Backlash between the teeth | 0–1 mm | 0.2 mm |
| Axle hole | 2–30 mm | 6 mm |
| Lightening holes (0 = none) | 0–10 бр. | 5 бр. |
| Margin of the base around the gears | 5–60 mm | 15 mm |
| Clearance between the base and the gears | 0–6 mm | 1 mm |
| Material thickness | 3–12 mm | 6 mm |
Material and thickness
GearSet is cut from plywood and other sheet materials. The material thickness can be set from 3 to 12 mm (default 6 mm); tabs, slots and clearances are recalculated automatically with every change.
Assembly
The parts are joined with finger joints: the tabs fit into slots and hold without screws. Kerf compensation is set in the configurator so the joint fits snugly; a drop of wood glue fixes it permanently if needed.
At standard dimensions the set has 3 kinds of parts; the configurator nests them on a sheet and calculates the cutting time and an approximate price.
Questions and answers
Which files can I get for GearSet?
For laser cutting – DXF, SVG and PDF with the layout of all parts; for preview – STL, OBJ and a PNG image. Files are downloaded from the configurator, and the terms are on the “Pricing” page.
What dimensions can I set?
Dimensions are set in the configurator: module 1.5–8 mm; teeth on the first gear 8–80; teeth on the second gear (0 = single gear) 0–120. The configurator recalculates all parts automatically and shows the 3D model in real time.
Which material and thickness should I use?
Plywood and other sheet materials from 3 to 12 mm thick work well; the default is 6 mm.
Do I need glue or screws?
No screws are needed – the parts hold with their own tabs and slots. A drop of wood glue is optional, for a permanent joint.
How many parts are in the set and how long does cutting take?
At standard dimensions the set has 3 kinds of parts. The configurator nests the parts on a sheet and shows an approximate cutting time and price for your machine and material.
What you get
- A flat cutting layout of every part – DXF, SVG and PDF for laser cutting.
- A 3D model for preview – STL and OBJ; a free PNG.
- Kerf compensation, press-fit tabs, text and logo engraving.
- Nesting of the parts on sheets and an estimate of cost and time.
