Why we test twice
The first test asks whether an idea can move. The next asks whether it moves for the reason we think it does.
Small mechanisms, plainly explained
parttinkerpuzzle.garden is an independent informational website for patient beginners and hands-on hobbyists. We explore mechanical puzzles through everyday prototypes: notched parts, hidden catches, tilting mazes and physical movement rules.
Our focus is the meeting point between pieces. A tiny ridge can disguise itself as a difficult puzzle. A small clearance can turn an unreliable mechanism into a repeatable one. We explain those differences without treating frustration as a measure of intelligence.
Prototype before polish
The guides begin with visible, accessible mechanisms and inexpensive materials. Example dimensions are starting points, not universal manufacturing tolerances. Your stock, tools, finish and environment will affect the fit.
We favour testing one variable at a time, preserving a recovery route and documenting what changed. We do not claim that every suggested material combination has been independently tested or certified.
A reading shelf, not a claim of invention
Mechanical puzzles have a long, shared history. These names and resources provide useful context for further reading; inclusion does not imply affiliation, approval or endorsement.

Safety stays part of the build
A puzzle guide cannot evaluate your tools, workspace or experience. Follow manufacturer instructions, secure work properly and seek competent help when a process is unfamiliar. Stop when a part needs force or a tool setup feels uncertain.
Our catches are not security devices. Our projects are not certified toys. Small parts, glass, cutting tools, dust and adhesives each need their own precautions.
Corrections are useful workshop notes
If an instruction is unclear, tell us which step and what you observed. Include the actual material thickness and the direction of movement. A precise description helps distinguish a wording problem from a material-dependent adjustment.
We do not offer emergency assistance, accredited training or guaranteed individual design review.
