This is a toy garage I designed and made for my kid.  The garage door can open and close.  There is a ramp to the garage door entrance.  There is a cone to hold traffic cones.  (I have a traffic cone model, you can also use).

There will be seven pieces in total that need to be assembled.  You'll need to print two garage door holders.

I know not every printer is calibrated to submillimeter precision, so there is a little extra space added for the pieces to fit together more easily.  You will need to glue them together.

The sign on top can fit a piece of paper with a custom design.

I printed on an Ender 3 V2.  The base is close to the max size.  Printing it flat with a skirt or brim caused problems, so I had to print without them.  I found the roof and the sign were the only ones that required supports.

I think assembly is straight-forward, so hopefully no detailed instructions are needed.
