A cool looking and easily built 30" rod

This is especially done for the archery lovers out there. Greatly inspired by the Gau-19 gatling gun, here are some goals I set for the project:

• Sexy looking: Works or not, you will have a neck-turner rod to show off at the range :P
• Cheap, easy to print, easy to built. 3 carbon arrows, 2 bolts, a few nuts and a bit of PLA. Well under 20 bucks.
• Functional: It must, to an extend, be able to flex, bend, absorb the shock of your shots and slow down the sight float. The triangular geometry and carbon shafts do an excellent job in this.
• Customizable: Fits as many people, shooting styles and bows. You can print the 80mm or 100mm 7.5mm diameter short rods come in the file if you dont want to make a long rod at all or you dont have spare arrows.
• And light as a breeze. Coz its made of plastic and carbon of course ;)

What you will need:

• 3 Old arrow shafts (7.5mm) diameter of any length as the rod.
• 1x UNF 5/16*24 2inch bolt, M8 washer and a nut. It goes into the stabilizer socket on most bows so, sadly, we have to comply with the Yanks' standards here.
• 1x M10 90mm use as counter weight. Add as many nuts as you like to increase the weight.
• Silicone glue. Strong, flexi, easy to clean and replaceable.
• Black electrical tape

Some parts are novelty and aren't necessary to be printed at all.
What you will get:

• Stock: This houses the UNF bolt that connects to your bow
• Brace: These pieces with keep the shafts from over bending and torquing. Print as many as you like.
• Spring Coil: We don't have fancy rubber material here so I stick with good ol springs for shock absorber. Refer to my photos and hutch914's spring form customizer on how to build this part.
• Barrel: This houses the springs, the M10 nuts and bolt and the whole thing acts as the shock absorber. Two springs, placed opposite each other, pre-compressed by the nut and bolt. The weight of the bolt, in turn, is suspended by the springs. The shock will be counter act by the bolt floating freely in the barrel chamber. I named this OSS (opposition suspension system) haha should I patent it ?
• Muzzles: All muzzle caps are for show :) Tho the suppressor can be filled with cotton balls or something else. Perhaps it would work ?

Customizables:

• Change springs winding and length to get your desired flex for the bolt.
• Add, subtract nuts to change weight and fit your bow. I think the heavier the bow, the heavier weight you need to balance it out.
• Cut your arrows or use other material (PVC, Aluminium pipes?) to change the rod length.

Review:

I have test used the stabilizer outdoor. It adds a bit of wobble on draw. But aiming is great. Sight float is slow down especially when my arm got tired after many shots. Follow up is nice too. I have never owned a long rod so I can't tell any more about the difference.
