The part that understands your hands.

A clip-on document camera for MacBook Air & Pro. It perches on the lid, points down at the keyboard, and feeds the fingering tracker — so TypingLens can see which finger hit which key.

The full kit, on sale shortly.

A printed mount, and a mirror, — assembled, shipped in a box. For anyone who'd rather not own a printer.

A clip, a hinge, a lens.

A three-piece print that doesn't modify your Mac — it braces on the lid, pivots forward, and aims a camera down at the deck. The hinge angle is what matters: too shallow and you miss the home row, too steep and the thumbs fall off the frame.
