V.S.T.O.C.K Spring/Pump Shotgun Mod - Quest 3

This is a simple mod to add a spring to A_Ls gunstock design. The original design allows you to use pump shotguns just fine but this mod adds some resistance while “pumping”, springs you back to position without the need to manually pull the controller and helps with stability while on the extended position.

It's a mild spring, you don't need much force to operate it. However I do still recommend adding lubrification to make everything smoother.
You will lose some travel with this mod (around 26mm).

I remixed the sphere so it's easier to print and locks to the aluminum profile (no longer requires glue), the main controller holder (removed portion of the lip for comfort and added a hole for the IR receiver) and front controller holder (removed portion of the bottom section for the IR receiver). You can use the original files if you wish.

You'll need 2 more M5 grub screws if you use my sphere design.

Printing:

The springs don't require supports as long as you use a small layer height (I recommend 0.08 or 0.12 max) and also print it slower. I printed mine on the P1S with 4 walls and 80% infill with decreased speeds (50-60mm/s on the coil section).

With that said, it still get's wobbly the higher it goes. So if you are being unsuccessful with the full 65mm spring, print 2 of the 33mm ones.

Print the “sphere_spring” with strong settings, since it can potentially break on the neck of the sphere.

I printed everything out of PLA, 0.08 to 0.2mm layer height, 4 walls, 40-80% infill. Supports added for the controller holders.
