EXTRACTED KNOWLEDGE / HOW-TOFROM CONVERSATION
QUESTION / CONTEXTI want to redesign a can crusher so I can print it. Id like to be able to mount it on a wall. Im not sure if gears or levers would be more durable
IMPORTANT GUIDANCE
*Lever (recommended)
Pros: fewer moving parts, tolerant of misalignment, easy to reinforce with metal pins/bolts, quieter, simpler to print/assemble.
Failure mode: cracked pivot ears or bent handle (easy to overbuild).
Best for: “kids/guests will use it” durability.
*Gears
Pros: compact, can multiply force in a small envelope, can be one-hand with a crank.
Cons: tooth wear, backlash, needs better alignment, needs real bushings, and printed teeth don’t like shock loads.
Best for: you *want* a crank feel and are OK adding metal shafts/bearings and occasional maintenance.
