Ontos Ducky Stock (It holds a spare Magazine!)

Since the fully extended stock of the Ontos is still too short for my liking, I modeled this new Stock.

The Ducky Stock

The Ontos by Impulse Ungineering is an amazing foam dart blaster, but the original stock is even fully extended a bit short for my liking. I present to you the Ducky Stock, which is 65mm longer and brings a new look to the blaster.

But most Importantly: It has a compartment for an extra 10x Worker Talon Magazine!

Slide the mag into the slot and click it in by pushing it against the top (you might need some force).

This feature only works with Original Worker Mags.

If you use different Mags, look into the remixed rubber retainer: 

Feedback appreciated!

To fully dial in the tolerances of the compartment, I’ll need your feedback. It does work amazingly with all my Worker Talons though.

Printing

Use Tree Supports! Everything other is up to you. I chose 3 Perimeters with 25% Cubic Infill.

Required Hardware:

1x M5x30 Pan head screw

1x M5 Nut

3x M3x10 or M3x12 Pan head screws (Hardware from the Ontos)

Important:

The M5 screw and nut only serve as a „key-piece“. Tightening the screw too much may cause damage to the stock.
