A unique Flywheel The World powered sidearm with a focus on ease of printing and hardware accessibility.


The DvZ Concept Pistol is a unique Flywheel The World powered, 3D printable sidearm with a focus on ease of assembly and hardware accessibility. It uses Worker Talons and compatible magazines for half length Nerf Darts.

This Blaster has been made available for free thanks to donations and my supporters on Patreon. For your convenience the checkout process has been drastically simplified for orders with a sum of 0€, so no payment, billing or shipping information is required. Nonetheless I would appreciate if you could support this Project by Paying what you can.

Compared to other printed sidearms it features less moving parts, minimal required Hardware and a lower total part count, as well as optimized printing directions for every single part. All parts of the Concept Pistol are printable without the need for supports and fit a standard 200×200 printbed.

Required Vitamins (non-printed parts):

    • 20x M3x10 Screws (Lens or Cylinder Head)
    • 1x M3x6 Screw (Cylinder Head)
    • 2x M2x10 Screws
    • 1x 5A Microswitch
    • 4x M2x4 Screw (Countersunk)
    • 2x 130-size  Motors (when using Powerful motors, a MosFET Board is recommended)
    • 1x Pair of FTW Flywheels

A formfitting Talon/Katana Hybrid Magazine is available for download with my Equalizer Magazine Pack.

If you want to modify this model and make it your own, consider purchasing the Concept Pistol Developer Kit.

    Quite a fun build! A satisfying combination of 3D printing, assembly, wiring, soldering, and finishing. With 3S batteries, can hit impressive FPS. I’m using 2S batteries so they’re more kid-friendly. The hardware are all relatively easy to source, and the prints are quick. The only part that needed supports was the cage. Minimal soldering and I managed without helping hands or clamps. Just used whatever I had at hand to prop and stabilize the wires as I soldered. Make sure to have a small file, sandpaper, and silicone grease on hand to adjust the blowback mechanism because everything relies on the slide moving smoothly.

    Couple of tips:
    – Use a file to chamfer the edges of the faceplate everywhere the slide rubs. This was where I had to focus the most effort in getting the blowback to operate.
    – I shimmed the DB2 switch arms with some layers of tape to rev the motors earlier. Gives them time to get up to speed before the pusher feeds a dart.
    – The post on middle2 that the pusher sits on is too large. Use a file to reduce the circumference, and grease it. Test fit with pusher until the pusher can turn freely before screwing things together.

    Suggested improvements:
    – A way to prevent the spring from falling out.
    – Include several variations on pusher to actuate the DB2 switch earlier.
    – Reduce size of post on middle2. It doesn’t have to be a tight fit. Just has to keep pusher in place until it engages with the slide’s gearing.
    – Getting the slide on and off is still clunky. I have to force the slide walls open to get around the motors/wiring/frame.
    – Clean up the dart’s exit path. There’s a lot of protruding plastic that can interfere with the dart’s flight.
    – Redesign the faceplate so that it doesn’t interfere with the slide blowback.
    – An indicator on the cage for flywheel motors’ alignment. If you press them too deep, darts don’t feed as well and it’s hard to bring them back out.

    Thanks for making the matching magazine files available to download as well! Those printed and worked without any problems at all.
