Large-Head Key Duplicator Remix

This is a remix of the manual key duplicator. The original design works great for standard keys, but modern car keys—specifically thick, oversized Mazda transponder keys—do not fit properly in the stock carriage jaws.I modified this entirely in Tinkercad to make it a more robust and flexible tool.🔄 What's Changed in this Remix:Widen Carriages for Mazda Keys: I sliced the main key holder carriage into two independent pieces and widened the pockets to provide ample clearance for oversized, thick plastic key heads.Lengthened Base: The main base plate has been significantly lengthened to accommodate the wider footprint of the new key carriages and provide a more stable cutting stroke.Integrated M4 Threads: Added built-in M4 metric ISO threaded holes directly into the key holders. This allows you to lock the positions down tightly onto the 8mm linear rod using standard M4 set screws or bolts without needing complex captured nuts.🖨️ Recommended Print SettingsBecause this is a functional mech
