Catapult

this is how to build my catapult!

step 1: make the frame axle and the launching system as shown on the pictures.

step 2: put the files on a memory stick now start the 3d printer. make sure all the peices are in seperate files that will save you a lot of time.

step 3: after the printer is done you have to glu the axle together while the axle in in the frame. make sure the glu you use is strong because otherwhit it will become loose again.

step 4: put you elastic in place. you can chose how many elastics you use. if you use alot of elastics there wil be more power, but if you add to much changes are that the catapult will break.

now you have your catapult.
