I have another free original papercraft template available: The Holy Hand Grenade of Antioch. The Holy Hand Grenade is a fictional Christian relic that appears in the 1975 comedy Monty Python and the Holy Grail. In the movie the relic is used by King Arthur and his men to dispatch an ill tempered rabbit who guards the Cave of Caerbannog...
Building the hand grenade is not as easy as it looks. While I think a few build imperfections add to the "rustic Medieval charm" of the model, those who are more perfectionistic will want to be well rested before beginning or they may find themselves throwing the unfinished grenade against the wall in frustration. ;) Here are the model details:
Finished Size (with base): 5" (12.7 cm) x 9 1/4" (23.5 cm)
