About this model

Full instructables here: The design intent here was to create the smallest slingshot that you'd actually want to use. (Of course you can just use a rubber band and two fingers but that sucks). This one works really well despite its small size because when you straighten your elbow and lock your arm the device is held super steady. I gave a set to my nieces with a big bag of mini marshmallows for Xmas. Ive seen a lot of creative slingshots out there but not one quite like this. In any case the 3d printed TPU pouch works wonderfully as an easy alternative to handmade leather. Sizes: XL-23.5mm Dia index, 24.5mm middle finger MED- 21.5mm Dia index, 22.5mm middle finger SML- 17mm Dia index, 18mm middle finger The rubberbands we used: Our TPU filament of choice:
