The Sliding Legolini crossbow is a pump action repeating crossbow that can be produced with commercially available 3D printers. It is based on the ideas of the famous Youtuber Jörg Sprave and was optimized for 3D printing by Łukasz Janikowski.

In the standard configuration, the magazine holds 6 arrows, which can be fired via the thumb trigger. Reloading takes place by pulling the handle forwards and backwards. You can shoot 6 arrows within a few seconds. The crossbow is optionally available with quick-loading magazines, which significantly reduce the refilling time of the magazine. The power of the shot is realized with this model via black TheraTube straps.
