This is a mini print in place forklift, I've been through a few designs before coming up with this final one.

The “fork” is printed separately and just needs to be slid onto the mounting poles,

Also a little box for the forklift to pick up is included, however this needs to be printed at 0% infill to be light enough that the forklift doesn't fall over - I also lowered the amount of top/bottom layers to 2. I might design some more things to pick up if so I'll add them to the files.

The main forklift is printed at 50% infill, however if time is not an issue making this 100% will make it be able to pick up heaver objects without falling over.

Finally this can be a bit tricky to print well given the thin areas and the roof which involves a lot of bridging so good luck!
