Want to customize your car or your bicycle? To make a naughty gift to your friends? The penis valve is the crazy accessory you need. Designed for presta valves, it can be mounted on a bike or a car equipped with these valves. Its height is 3cm and its width at the balls is 1.5cm.
I recommend using a solid plastic (PLA). Place the cap vertically for printing. Filling: 18%. Print speed: normal (if you notice defects, decrease the speed). Adhesive plate: YES (especially if you print the model in ABS). Support : NO. Plastic required: 2 grams. Print time : depends on your settings.
