Slice the stl file with your favorite slicer-we run one outer perimeters at 100mm/s and use 35% fill with Slic3r.

Note: No support is necessary if you have decent bridging ability.

After the part is printed, use an exacto to trim as necessary.
To clean up the holes (and make assembly easier), use appropriately sized drill bits.
Thread 1 M4x25mm bolt through the catapult base (optional opening for M4 nut on the opposite side included).
Then thread 4 M3x10mm bolts through the wheels and into the corresponding holes in the frame.
Attach a rubber band around the catapult and bumper and you are good to go!

Be careful not to hurt yourself or anybody else – this a tough design that can launch items up to 20 feet!

Note:  The catapult below was printed with a larger model 3d printer – the AW3D XL.
