This is a Customizable Vive Rifle made using 2 types of screws+nuts, 1/2" PVC Pipe, and 3D printed components.

I have designed this setup to be lightweight, easy to print and assembly, and most importantly, easy to use while in VR. The rear controller is fixed in place when using this setup and the front controller is removable using a quick connect attachment fixtured through the "donut" of the controller. Included are the files for an optional Shoulder strap.

• This setup will work with both a rifle and a pistol in games such as Onward and H3VR.

I have tested this in H3VR and found that the only guns which do not work well are the ones where the magazine is behind the grip, since that space is taken by PVC in this design. I have not found a single rifle or pistol in Onward which did not function perfectly

To use it as a pistol you can use the optional shorter barrel, or simply use it as is. If you need to two hand a pistol (for example onward) you can attach the second controller as normal, then slide it back until it contacts the front of the rear controller, this is within the trigger distance for getting two handed mode in Onward. If you wanted you could then slide it forward and use your pistol like a rifle (it feels strange like this but it is effective).

Assembly instructions are detailed out below.

Rostock MAX v2

No

Yes

0.1-0.3 mm, It really shouldn't affect anything

10-30% should be adequate

Support:

Needed inside the "Bottom Cup,"

• I have found that really just the center needs support (where there is a groove for a wrist strap), if you fill it with too much support it will become difficult to get out.

For the other components I used support inside the screw holes, and under significant overhangs, this will vary based on your own printers as to what is necessary.

Material:

• I recommend PLA for the quick connect feature, this is the one feature that really relies on the material properties to get the "feel" right.
• I recommend a softer material than PLA (ABS or EDGE) for the "Bottom Cup" feature. This is simply because PLA can be slightlly scratchy on the surface of the controller, so if that is something you care about keep this in mind.

I am putting this at the top for convenience.

YOU DO NOT NEED A SCREWDRIVER FOR INSTALLATION OF THE CONTROLLERS.

Since both controllers are held in place with a Hex head fixed inside of a printed part it can be easily installed and removed.

To remove the rear controller you just need to use the controller screw (the one inset within the Printed part). If you unscrew this the controller can be pushed out.

This screw can be tightened quite tight, I have not had any fear of breaking the controller as of yet.

I highly recommend using the customizer version I have included to get the exact dimensions of your fasteners, it will be a more convenient experience. For some reason the Preview in customizer only shows the rear of faces, I do not know how to fix this however the parts will come out fine from the customizer.

• The customizer will produce one of each component when run, they will be saved as individual .stl files

• The .stl files included on this thing are for the default settings of the customized part. These are the dimensions I used for my Vifle.

When sizing the screws in customizer I recommend to measure the dimensions and add at least 0.5 mm on top of that. With my printer and my experience I have found that to be a suitable tolerance to get a nice fit with screws in my printed parts. This value may be different for each printer.

Please print the quantities as follows:

1x Top_Quick_Connector

2x Shoulder_Strap (Optional)

2x Center_Screw_Bottom

1x Top_PVC_Connector

1x Rifle_Stock

1x Bottom_Cup

You will need 2 types of fasteners for this and 1/2 inch pvc pipe. Lengths can vary for these screws but should be as follows:

6x Pan Head Screws (+2x total if using shoulder straps, can be used without screws)

• recommended 1.25 in or 30 mm length, can be longer (you may scratch yourself on the protrusion)
  • I personally used M4 x 30 mm Screws

6x Hex Nuts (+2x total if using shoulder straps

• to match pan head screws

2x Hex Head Screws

• recommended at least 1" or 25 mm long, max 35 mm long
• I personally used 1/4" - 20 x 1" hex head
  2x Hex Nuts
  • to match Hex Head Screws

links added for clarity, I recommend actually purchasing these through a local hardware store for price and convenience:

5ft 1/2" Standard PVC Pipe

• I have attached a photo showing all the components and their basic lengths .

2x 1/2 " 45° Elbows

Other Notes:

• The part attached to the "Rifle Stock" can be adjusted based on your arm size
• The "Barrel" of the rifle can be made longer or shorter depending on your needs.
• An alternate length of the Barrel is included for "Pistol Mode" where the Barrel is shortened for convenience.

For the shoulder strap I use: https://www.amazon.com/dp/B01E13DFRG/ref=cm_sw_r_cp_ep_dp_Qy9LybD9EESWS
I found this strap to be the right combination of length, price, and comfort.

I will re-iterate, this is NOT necessary for the assembly, I have included it as people often want a way to drop the controller. I do not use this regularly as I find it to be cumbersome.

I found that press fitting the PVC was all that was needed for strength. It also makes it very convenient to swap out components if desired.

You will need to drill a through hole for each of the screws used on the PVC connectors. - The easiest way is to assembly the components and use a sharpie to mark each side of the hole you want, then drill each side through (DON'T drill through both sides unless you are using a drill press, they will not line up easily). Once each side has been drilled use the drill to go through both sides at once, so as to remove any burrs and misalignment.

Be sure to test assembly with the controllers installed before drilling all the holes. Some variation from the PVC lengths I listed may be needed depending on your exact setup.

Assemble according to the attached photos, it should be self explanatory where each piece goes based on my exploded view.

I recommend having the "Bottom_Cup" slightly more forward on its PVC pipe than expected. This will effectively apply a pre-load on the controller and reduce the amount of wiggle from the PVC.
