The NG-3 'METEOR'; our first rival blaster
For this blaster we had to iterate ourselves through 17 different versions. Most deisgn solutions implemented on half- or full length darts where not applikable due to the different type of ammunition. Lets quickly dive into the main design drivers of this blaster.
Plenty of concepts have been investigated. Many of them were even manufactured, tested and improved upon.
Semi- or full auto
Rival ammunition has no directional preference if compared to foam darts, which have a preferred travel orientation. The rival ammunition can basically enter the fly wheels from any direction. So instead of having to align the magazine vertically, it can now be aligned horizontally with the main body of the blaster. If unlocked, the mag will now feed all balls into the fly wheels. Basically, you immediately end up with a full auto setup. One downside however, is the extensive rate of fire, which is basically uncontrolled. This proves to be problematic if your ammo capacity is limited. So with version v14 the design was revised to a semi auto action; Each trigger pull will launch a single ball. The main challenge here was to accomplish this without adding a complicated mechanism. So in the NG-3 the semi auto action is achieved without additional geared motors or solenoids.
Trigger pull and rate of fire
So with semi auto, you will be able to use your ammunition very economically. But, in order to still achieve a high rate of fire if necessary, the NG series uses a trigger return with linear force increase. This results in a very smooth and fast action. Initial designs had a single trigger which would also spin up the motors. The final design does however feature a separate rev trigger, which adds a little bit more control.
FPS
Currently, the NG-3 reaches a max 100fps with a 2s lipo setup. Ball type ammunition has a much shorter acceleration length compared to foam darts. So for the NG-3 the fly wheels had to be changed from the ground up. They are still 3D printed entirely in ABS.
Accessibility
The NG-3 feature a battery door at the rear of the main body. It does not require any tools to open it.
Additional features
Similar to the NG-2, the NG-3 will except 2s lipos measuring 58x30x15 mm. Both the 'Graphene 2s 950mAh 65c' from Outofdarts and the 'Turnigy Graphene Panther 1000mAh 2s 75c' from Hobbyking also fit.
The nozzle has a built in thread, allowing the installation of e.g. a hop-up or any other kind of barrel extensions (see image below for dimensions).
There is the possibility to also add a rear cover for those who prefer that option. But it is currently not part of the offer.
As usual you will find the NG-3 here in our online store
or on ETSY.

The EMW A-6 looks definitely cool enough to justify making a model kit for it. And as far as I know, there is no 1:48 scale model kit on the market currently. Some information from the www.nevingtonwarmuseum.com:
Damit Eure Kekse mit unseren Backförmchen so richtig gut funktionieren haben wir für euch ein paar Tips zusammengestellt. Vorab einmal das Rezept: 100 g Butter 50 g Puderzucker (kann dem eigenen Geschmack angepasst werden) 30 g Ei 200 g Mehl Die Mengen können unter Einhaltung des Mischungsverhältnisses erhöht werden. Zunächst wird der Puderzucker mit der Butter vermengt. Danach wir das Ei hinzugegeben. Anschließend wird das Mehl untergehoben. Wichtig: Damit der Teig die richtige Konsistenz erhält sollte er gekühlt werden; ca 30min im Gefrierfach oder 1-2 Stunden im Kühlschrank.
The PATHFINDER is essentially based on the standard NG-2. But it features a full auto mechanism, voltage indicator and safety catch. Max fps is 130, the rate of fire is approximately 900darts/min.
The NG-2 GOBLIN was designed in 2019 and basically follows the design philosophy of the original NG-1. But, as always, you learn. So the NG-2 was an effort to reduce the overall complexity of a blaster while optimizing it for easy printing and quick assembly. After all, 3Dprinting is rather scalable by simply investing in new machines. However, post processing, assembly, testing and shipping quickly become bottlenecks in production.
We use 3D printers to produce our products. There are different types of printers and countless different processes. We have specialized in what is sometimes revered to as FFF (fuse filament fabrication). The process is rather cost effective and uses a simple process of depositing a thermoplastic material layer by layer. 3D printing technology used to be locked down by patents for decades, limiting the technology to large and costly machines. Once those patents ran out, a new generation of desktop printers started to emerge. These machines are rather simple in design, but manage to output parts with astounding quality. Also, due to the small investment costs, the process can now be parallelized which has a profund influence on production costs. At the core of all this, is the material. After all, it is the material in combination with a specific design that enables a desired functionality. And today, in 2020, PLA or 'polylactic acid' is one of the most widespread materials in desktop 3D printing. PLA outperforms almost any other material in this category in terms of strength and stiffness (yes, those are two different things ;)). An interesting comparison is published by simplfy3d here . This is especially true if we take into account the directional dependency of the material properties which is introduced by the FFF process. Out of plane strength, i.e. layer adhesion, suffers greatly for most materials. The overall knock down for PLA is relatively low.
