This is a simple card construction kit for a jumping frog. 

To assemble, remove all parts from the tabs.

If any of the slots fuse shut, just pry them apart.

The slots on the long legs go onto the slots at the back of the frog. Similarly the short go to the front.

All parts required are included in the print, and no additional tools are required for assembly, although optionally a pair of scissors or other cutters can be used to assist in tab removal.

To make the frog jump, just press down on the back, and slide your finger off.

The model should be printed with no brim, and no horizontal expansion. 
The model has been tested with PLA, on a .4mm and .6mm nozzle.
