Leonardo Da Vinci Catapult

PLEASE READ ENTIRE DESCRIPTION BEFORE PRINTING! Hello, welcome to the leonardo da vinci catapult that I designed. I did add two extra tension arms to increase the strength of the catapult. In order to make this yourself, you will need PETG and also some string. Link to parts needed:Bearings: https://a.co/d/4Mq5sLK String: https://a.co/d/9Q3gmXp HOW TO ASSEMBLE: First. insert the 4 tension arms into the slots at the base. Note that you want the whole of the tension arm to be visible, NOT in the base. Also note that this is a pretty tight friction fite so you will need to push hard. This hole did not come out as clean as I would have liked, so I ended up having to use a 1/8 inch drill bit to clean it up.Once cleaned up, make sure that this green piece fits in the hole. Next, you put the green pin in the blue arm and all that into the black base. I did not glue this, in that if it ever broke I want to be able to easily replace it. <figure class
