3D model description

The UMAREX HDS 68 defence rifle uses a Co2 sparclette and can fire 2 .68 calibre rubber bullets (or Paintball) with a power of 16 Joules.

I created this cartridge to fire projectiles other than this rubber bullet...

My first paper-tube version is here:

...but the disadvantage was that the entire cartridge was ejected and therefore lost...

I propose here a new version of cartridge which, after the shooting, is recoverable for a new load.

It is made up of 3 elements:

  • 1 cartridge

  • 2 covers which close the cartridge at its base and at its end

You will find 3 versions of this cartridge in the Zip :

  • a 40mm Big version to load 23x BB 6mm airsoft

  • a standard 26mm version to load 14x BB 6mm airsoft

  • a 16mm Mini version to load 20x 4.5mm steel balls airgun ...

... but you can load these cartridges with flour, pepper, confetti, salt, etc ...

How to proceed :

  • Print cartridges and lids

  • Place a cover at the base of the cartridge and fill it with the chosen projectiles.

  • Seal with a second lid and just 2 dots of white glue (school glue).

After each shot, simply retrieve the cartridge and reload it using 2 new caps.


The use of these cartridges represents a much greater danger of injury(ies) than the original rubber bullet!

For example, here in France, if a possible assailant is injured, you risk criminal prosecution!

To be used only for recreational shooting!

My other ammunition for this weapon:

  • Rocket:

  • Shoe cartridge for a diabolo .177 :

  • Balls:
