Historically, the classic bow and arrow has been a specialized weapon requiring great efficiency, strength, and marksmanship. The crossbow later played a significant role in warfare. Today, thanks to Dick Cho and his efforts, it looks like the 3D printed modern day version is lending itself to a tremendous amount of boyish fun.
Reaping the rewards of a new prototype with further refinements, Cho and his buddies are having far too good a time shooting arrows at their pile of warehouse cardboard with his 3D printed compound bow while the rest of us are working.
The Vincy Compound Bow Mark 3 is obviously highly functioning and robust. The item sells itself in the video, making you want to get up off the couch and ask for a chance to draw the bow yourself. The creator and his buddies are plenty excited over the bow and although it’s not in English, you very well get the point that there is a lot of enthusiasm over the 10 meter test.
Cho states that this most recent prototype improves upon the Vincy Compound Bow Mark 2 with main new feature being the 4X 30/6/600 fiberglass used. The new Vincy Compound Bow Mark 3 also features:
- Adjustable cable tension device
- Drop away arrow rest 3d printed
- Power increased to 13KG
While he was also having a great deal of amusement with the last model, his Bow Mark 2, it was lacking some power (do take note that the compound bow usually has a draw weight of less than one-half of a crossbow). While Cho recommended ‘powering up’ by adding extra fiberglass, obviously he decided it was time to go back to the drawing board and create a new 3D printed prototype.
Cho invites you to download his 3D design from Thingiverse. The basic instructions are simple:
- Bolt the parts together with M3, M4, M8 screw and nut.
- Note that the Cam bearing is 608 bearing.
- Note that the fiberglass are 4 nos. of 30X6X600.
Cho considers himself to be a ‘prototype maker,’ and that sounds like a fitting title, as he is a great enthusiast of creating 3D printed ‘hi-tech and low-tech stuff’ with his 3D design and 3D printing portfolio so far consisting of a rail gun, ETG (Electrothermal Gun), crossbow, and the compound bow. He even 3D printed a wedding band.
