Urban ops STL file released!

Preface:

Hello, everyone on NH,I’ve been working on developing lately, so I diving for a while.

The developing of Urban ops started around this April. Here are some results that I would like to share.

Design:

The aesthetic of Urban ops is an old school combination of my wonderful visual and ergonomic experience from my childhood.

I’m inspired by these models:

1. LNL pistol is a recommended pistol on NH. I like the appearance of the grip a lot. So, I integrated it into the flashlight mount with a touch of bright purple.

2.TECH TARGET: The extended look of the sight has a techy vibe to it. The ergonomic trigger is well designed, perfect for gun spinning tricks.

3.NiteFinder: When I got it, the blue and orange coloring made me feel like a detective,

probably because the police wear blue uniforms. Since the small size fits in a holster easily,

I was hoping that I could do the same with my design.

4.M1911 Grip Panel: This is a design that realized customization. Each panel could be unique,

so that the users can express their own style, making it worth collecting

5.BERETTA 93R: It was the folding stock that impressed me.

The look of BERETTA in Robot Cop is also quiet outstanding.

Other ideas:

1. The color of Urban ops conveys a feeling of the night with purple and aqua blue.
   What’s interesting is that when we were taking photos of it, it merged into the night of the city.
2. Muzzle brake 
   The sporty design of the muzzle brake consists of different tringles.
   Among guns designed specifically for competitions, a lot of them have a muzzle brake with geometric design.
   I didn’t make rounded hole because they are very common.

Build- in SCAR BARREL

Actually, this is an old method of JSPB. In order to save space,

O-Ring is adopted in place of screws. It comes with 5R rifled barrels because it reduces the time of making.

Since a pentagon shaped rifling could be difficult to make without tools,

a STL file of the tool is thoughtfully provided! (Of course, a 6R one would be more accurate.)

1. Single shot pistol

1. The advantage of the single shot pistol is that it’s new player friendly.
2. So far, we are focusing on optimizing the basic functions. Since some people are looking forward to the wheel, it is under development. The wheel would be compatible with JSPB Urban ops.
3. You can keep it in your bag with you. Make nerf war a life style.

Folding stock connector

The folding stock connector is special because it is also a bottle opener.
Why? It’s all about catching up with friends. After a war, don’t go home straight away! Have some drink and chat!

Scope mount

Solid design, offers a steady and secure hold. Not shaky at all.

1. Parts marked with “100fill” should be printed at 100%.
2. Piston and piston rod should be printed with Pla2.0 or PETG
3. Compatible [[[[k26]]] (For safety reasons, parts should be defect-less)

Hi, remember the method of using fishing line for rifling by winding fishing line in the barrel?

I would like to publish a new version of ZLING Rifling. You can download the stl file to apply it to your work.

Features of this version:

1. Adjustable twist rate

2. Threads are held by screw. Fat-finger problem free. That is to say, no more tying!

3. Threads will not loosen.

WHAT IS ZLIN RIFLING?

2010, January 27th, Ezekiel Lin successfully make the dart spin with fishing line for rifling. The technique was named Antennae Rifling Barrel since after tying, the threads looks like antennae of insects. The threads can function as sensors, enabling players to observe wind direction while shooting.

DEVELOPMENT
2015 ARB is applied to JSPB Pro and renamed as Zlin Rifling. Knot tying parts are improved.
2016 Zlin Rifling is applied to JSPB Pro2. The original 4-line design is increased to 6-line, significantly improved shooting accuracy.
2017 Zlin Rifling is applied to JSPB B&B. Threads are held by a screw, hence thread tying is no longer required.

FEATURES

The standard internal diameter of Zlin Rifling ring is 18.55mm. Rings of 13mm and 14mm internaldiameter are also available.
​
(1) Standing poles, designed to make the screw stand whiling being fixed to the barrel.
(2) Blocker, prevents over screwing, also acts as a cooling conductor during 3D printing.
(3) Supporting arms, supports the frame.
(4) Grooves, holds lines.
(5) Taps, increases screw stability.

Zlin Rifling’s ring-shaped holder allows you to install barrels with various design. The distinctive feature of the barrel case is a long strip shaped hole for fine tuning.

 

FISHING LINE

materials and features introductions:
Line Diameter: 0.2mm (1.5#)
 
Braided Fishing Line: Some are made of PET+PE, absorbs water and has a high abrasion resistant.
Metal Fishing Line: Covered with a layer of plastic, which has a smooth surface that makes the shooting easily and creates vibrations like string instruments for rifling. However, the line will become very fragile once the plastic layer broke.
Nylon Fishing Line: Not recommended since it creates high resistance against plastic dart tips.

Hi everyone, I am 3DBBQ .  

I want to show you my latest project.

This is the hopper clip design. This is a mechanism that I have never made before because there weren’t any Pipe Wyes where I lived.

When prototyping, I used 3D printing to make the Pipe Wyes models. These are the areas where I have fixed the hopper clip:

1. The darts now start to turn after it accelerates instead of turning while it accelerates. This allows the darts to really go through every step without getting stuck or shooting blanks.

2. Using a spiral airflow to allow turning while accelerating.

3. 35 degrees is a good angle.

I use a bigger check valve instead of a mini valve for larger ones have greater pump force and power.

However, there is a problem with shooting compared to the mini valve, which is why I’ve designed a lever mechanism that can make you press easily and shoot with a strong force.

The hopper clip’s aiming scope is made of four mirrors to form a reflex sight that prevents the magazine from blocking the line of sight.

Conclusion: The hopper clip is a design that allows speed and high efficiency. It also solves the problem of an obscure line of sight thanks to the sighting device.

-------------------------------------------------------------------

This is the version of the big air tank I’m fixing now.

The big air tank can be used in many places, but I recommend to use it with an air tank big enough for better results.

This is how it works: 

Using a tiny cone to prevent the air from shooting out at once. The cone allows the air to enter the spacious air tank quickly, and leave the spacious air tank slowly. During the shooting process, do not press the trigger for too long so that you don’t consume and waste the air.

This is a design that is easy to make and it can allow firing shots in rapid succession.

Hello every one!
This is a new way to make darts
Made dart any tima any where, simple, Unplugged!
This is what I made zlin tool, there is a free 3D model download.


HERE: http://www.jspb3d.com/free-models.html

Currently the use of rubber,Resistance is relatively large, lightweight
Correction result FFKM O-Ring ,Heavier, more smooth.
