**📦[Keychain Blaster Gift Crate](https://than.gs/m/1155174?affiliateCode=Jaatinen3D) — a stylish storage and gift box that has an insert designed for this blaster!**

&nbsp;

_The Desert Eagle is pure excess — massive, unmistakable, and built to make an impact. More icon than sidearm, it’s all about presence._

&nbsp;

---

A compact Desert Eagle -inspired keychain blaster designed for maximum fun in a minimal form factor!

This tiny hand cannon shoots standard 6mm airsoft BBs and features a removable magazine with a 5-round capacity, making it surprisingly satisfying to load and fire despite its size. The design focuses on clean mechanics, reliable function, and a crisp tactile feel.

Perfect as a desk toy, fidget gadget, or just a pocket-sized conversation starter.

**Printing tips:**
No AMS required to make this multicolor, all the different colored parts are separate!

All the parts are already in the optimal orientation for printing!

The following parts require supports:
- _Frame_ — Normal supports
- _Hammer_ — Normal supports
- _Front Slide_ — Normal supports, just a little for the front sight

_Rear Slide_ has small built-in supports you have to remove before assembly.

I recommend brim for the _Rear Slide_ because it warps very easily at the back and the contact area is pretty small. It's also a good idea to use brim for _Barrel_, _Front Slide_, _Rear Slide Spring Cap_ and _Grip_ depending on your bed adhesion.

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

**Assembly:**
You'll need superglue and two small 5mm diameter springs 20-25mm long.

See the included assembly video (listed above the promo pics)!

Desert Eagle Keychain — Functional Blaster Toy

Frame.stl

The BinaryBin is a fully 3D-printable, snap-together locking container powered by a programmable 16-bit binary code. It’s part puzzle, part teaching tool, and 100% nerdy—in the best possible way.
**What Makes It Special:**

- Mechanical DIP-style binary switches (16 total) grouped into 4 nibbles for easy binary → hex conversion
- Orbital gear-driven lock system that only disengages when the correct code is entered
- Programmable mechanism lets you set your own combination
- Non-binary switch state lets you “erase” the visible code after unlocking
- Hexadecimal encoding legend built into the layout (great for teaching or learning)
- Concealed mechanical latches, controlled entirely by the geartrain
- Fully printable — no electronics, no glue, no screws

**Educational & Fun**
Learn (or teach) how binary and hexadecimal systems work—by actually using them. It’s a brainy hands-on demo disguised as a seriously cool lockbox.

**Ideal For:**

- Puzzle lovers & escape room designers
- STEM educators & students
- Nerdy gift-givers
- Makers and collectors of mechanical marvels

**Printing Tips:**
- No supports required – all necessary supports are built in
- Includes an optional tool for disassembly
- PLA recommended with standard 0.4mm nozzle
- Full print & slicer settings included in the images

**Code it. Turn it. Unlock it.** The BinaryBin isn’t just a container—it’s a hands-on lesson in binary logic, gears, and clever design. Post your prints, remix your codes, and share your builds!

**Revisions and Updates**
I occasionally update and revise my designs. When I do, I’ll document the changes here. Check back periodically for the latest revision notes or if you’re experiencing any issues with a model.  

2025-06-10: I have added non-AMS versions of the lid and switch plate.



BinaryBin – 16-Digit Binary Coded Lockable Container

This is a fully functioning 3D printed grandfather clock.  Using mainly 3D printed parts, this clock was specifically engineered to be assembled in minutes, and can run for over 6 days on a single winding. With a little bit of tuning, it can accurate keep time with that classic tick-tock sound.

The video below shows how easily this clock can be assembled 

**The STL File:**

Prints on all standard 3d printers without supports, requires the following additional parts to assemble:

- 21 M4x12| 11 M4x20 Screws (https://amzn.to/3zgQb8f)
- 23 M4 Washers (https://amzn.to/3E1crFU)
- 17 624Z 13mm OD/4mm ID Bearings (Like these https://amzn.to/3DtUUpH)
- 1mm Nylon String or Fishing Line (I used string from this set https://amzn.to/3DtUUpH)
- 5 pounds of weight - could be ball bearings or a dumbbell (I used one from this set https://amzn.to/3zfVKUy)

**Recommended print settings:**

Layer Height: 0.2mm
Nozzle: 0.4mm
Infill: 15-20% 
Material Required: ~650g (Printed in PLA)
Minimum Build Plate Required: 180x180mm


**All the files have been pre-oriented to save you some set up time! All you need to do is drop the parts into your slicer and hit print!

The 3D Printed Wall Clock

0 Entire Part Layout (For Planning).stl

The **PuzzeLock Box** is more than just a container — it’s a fully 3D-printed puzzle hidden inside a working lock. At first glance, it looks like a simple latch-box, but beneath its 2 mm-thick false floor lies a **programmable lock system** built entirely from printed parts.  

To open it, you’ll need to solve a sequence of steps:  
1. **Set the secret number dial** (42 possible positions)  
2. **Spin the box** to release the centrifugal latch  
3. **Slide the hinge into position**  
4. **Release the main latch**  

Only when each step is done correctly will the lid unlock.  
It’s part puzzle, part lock — and all 3D-printed fun.  

**Key Features**  
- **100% printed** – no hardware, screws, or extra parts required  
- **Programmable lock system** with your own secret number  
- **Unique puzzle sequence** – every opening feels like a mini adventure  
- **Snap-together design** with print-in-place latch  
- **Compact but useful**: inside cavity fits cash, cards, small valuables, or even a phone  
- **Great gift or challenge** – part puzzle, part secure stash  

**How it Works**  
- The **Secret Dial** (42 numbers) acts as a combination lock  
- A **Centrifugal Latch** with gravity weights forces you to spin the box on a flat surface  
- The **Sliding Hinge Section** controls both the dial and the latch  
- The **Latch Bar** at the front is the final lock, only freed once all conditions are met  

This layered system prevents “safe-cracking” by touch and guarantees that only the correct sequence will unlock it.  

**Specifications**  
- **Usable inside cavity**: 6.25" × 2.75" × 1" (158 × 70 × 25 mm)  
- **Outer dimensions**: 6.6" × 3.5" × 1.1" (168 × 89 × 28 mm)  
- **Lock mechanism thickness**: 2 mm layer in the floor  

**Printing & Materials**  
- **Box & Gears**: PLA  
- **Spring parts & False Bottom**: PETG (recommended for flexibility & transparency)  
- **No supports required** – built-in where necessary  
- **Print settings**:  
  - Nozzle: 0.4 mm  
  - Layer Height: 0.2 mm  
  - Walls: 4 (1.6 mm)  
  - Top/Bottom: 5 (1.0 mm)  
  - Infill: 40% Cubic (Box & Gears), 100% (Springs/False Bottom)  
  - Orientation: as per STL/3MF  

**Included**  
- STL/3MF files  
- Full 10-page **Instruction Manual** with step-by-step printing, assembly, and usage guide  
- Clear diagrams and pro tips for smooth operation

I occasionally update and revise my designs. When I do, I’ll document the changes here. Check back periodically for the latest revision notes or if you’re experiencing any issues with a model.  
2025-10-10: I have uploaded a revised version of the Box [100] with improved geometry, which should allow it to release more easily.  The new design includes a new small piece of removable support, which is shown in the new PDF document attached.   I have also significantly expanded the assembly instructions with addtional diagrams.
