Garage Keychain Holder For DieCast

Hello everyone!

This is the Hot Wheels keychain holder I designed.

It has been completely redesigned from scratch to ensure smooth and reliable operation every time.

The print orientation, assembly process, and number of parts have all been carefully optimized — only 3 printed parts are required.

First‑Use Adjustment

If the door does not close automatically at first, simply move it back and forth 20–30 times.
This will loosen the mechanism and allow it to work normally.

If it still does not loosen:

• Check that the pegs are round
• Remove any leftover support material
• Lightly round or sand the pegs if necessary

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

⚠️ Important Printing Notes

• Do not print the door using a rough/textured material
• Do not remove the 100% infill at the bottom of the door

Failing to follow these instructions may cause the mechanism to not work properly.
