Volex Labs / Forge / Timing pulley & sprocket generator — text to CAD.

Timing pulley & sprocket generator — text to CAD.

Describe a timing pulley or sprocket — belt profile (GT2, HTD, T5), tooth count, bore and flange — and Forge builds the correct tooth form and returns a STEP or STL ready to print or machine.

Belt tooth profiles are generated to the real standard, so the pulley runs true and the belt seats properly.

Frequently asked

Are the belt profiles to standard?
Yes — GT2, HTD and T5 tooth forms are generated to their real pitch and profile, so a standard belt seats and runs correctly.
Can I print it?
Yes, the STL is print-ready; most makers print GT2 pulleys directly. STEP is there if you'd rather machine it.
Bore and set screw?
Both are parameters — set the bore diameter and ask for an M3/M4 set-screw boss and it's built in.
