Ever since I made the [Tickler BB-13](https://than.gs/m/1034516?affiliateCode=Jaatinen3D), I've wanted to design a double barrel shotgun using the same mechanism. Here it finally is and it's ready to kick ass!

See it in action here: https://www.youtube.com/watch?v=xsVJvoRTt0Y

Includes a complimentary **Shotgun Shell Weapon Charm**! The weapon charm chain has an end clip that is compatible with all my Ringchaku designs, so you can attach any Ringchaku end to it! Although most of them are probably too big... But stay tuned for more weapon charms in the future!

**Assembling this requires no glue or bolts or nuts! Apart from the printed parts, you'll only need:**
- One pen spring *(max 5mm diameter, 15-20mm uncompressed length, <9mm length compressed)*
- Two rubber bands (10-30mm diameter)

**Printing tips:**
All the parts are oriented in the correct printing orientation.

Use supports for *Trigger Assembly Cover Left* and *Trigger Assembly Cover Right*. All others are up to how your printer can handle small bridges and overhangs.

I recommend printing the *Barrel Lock Latch* in a "slippery" filament (not matte) because otherwise you might not be able to slam the barrel closed due to friction between the barrel and the latch.

**Assembly:**
Watch the included assembly video!

If you don't have BBs, I've included a printable bullet that works at least as well as a BB!

Rutku BB-20 — Fully 3D-printable airsoft shotgun with shells

Rutku BB-20 - Bambu Printers.3mf

Shotgun Shell Charm.stl

Ringchaku Charm Chain.stl

Cute miniature toy tank inspired by the Soviet KV-2 tank, with functional treads, a turret that shoots printed ammo and a trunk that stores 6 shells!

&nbsp;

---
**Printing tips:**
The parts are already oriented optimally. _Main Body_ and _Turret Body_ require supports. I recommend tree/organic supports for _Main Body_ and normal supports for _Turret Body_.

If you're using Orca Slicer or Bambu Studio, a handy project file is included that has my print settings and painted parts ready to go!

&nbsp;

---
**Assembly:**
You need a 0.5x5x20-25mm spring for the turret shooting mechanism and maybe glue for some parts depending on your tolerances and materials used. All the parts are snap-fit though.

See the included assembly video!

QT-2 Tank Toy — Mini tank that shoots!

Main Body.stl

Little brother to the [Tickler BB-13](https://than.gs/m/1034516?affiliateCode=Jaatinen3D) and [Tickler SA-6](https://than.gs/m/1066044?affiliateCode=Jaatinen3D), but this one is spring powered and ejects the shells automatically! It's half blaster, half satisfying fidget toy! Works with both 3d-printed bullets and 6mm airsoft BBs!

---

&nbsp;

**Printing tips:**
All the parts are already aligned in the orientation they should be printed in. The _Frame Half 1 & 2_, _Firing Pin_ and _Trigger_ require supports. _Slide_ has small built-in supports you need to remove after printing.

If you use Bambu Studio or OrcaSlicer, a handy print project file is included with the print settings I used to print this (many times)!

---

&nbsp;

**Assembly:**
You'll need __two pen springs__, __one stronger spring at least 25mm long__ and __one small rubber band__ to assemble this! Watch the included assembly video to see how it's done!

**Introducing my articulated Tortoise design!** It's been quite a fun challenge to design of a tortoise that could both stand and retract into it's shell!

It's fully print-in-place, you just have to crack the head free (similar to the bunny and tiger). To help him stand, there are small ball and socket joints on the ends of the legs. Just pull the legs out as far as you can, and they should snap into the position that will allow them to support it's weight. Then pop them back in to let him hide back in his shell. (The first few times might take some extra effort, but they should break-in nicely)

Here is a **[demo video](https://youtu.be/SYsawWpqvkY)** of the model!

Multicolor 3mf included (works in PrusaSlicer and Bambu Studio)!!

Printing Details

-   Print-inPlace: no supports
-   Multicolor 3mf included! (will load in Bambu Studio or Prusa Slicer)
-   3 Walls
-   10% infill\
Pulling the legs out fully allows them to pop into sockets. That creates enough tension to make him stand up.  It may be difficult the first few times, but once it breaks-in, it should work with light effort.  The head has built in pre-supports, just twist the head after printing to crack the joint free.\
Here is a **[demo video](https://www.youtube.com/watch?v=SYsawWpqvkY)** of the print.\
This should generally scale down to about 60% with full articulation, on a well calibrated printer. Your mileage may vary.

**This model was designed for FDM printing. It was not designed for Resin printing, and I cannot guarantee good/functional results. Resin print at your own risk.*
