This is _version 2.0_ of the game, with many exciting upgrades:
- All parts newly redesigned and 50 problems in total!
- The 'bits' have larger hinges that are stronger, easier to print, and fit into the problems more visibly. 
- The bits and problems can no longer be placed upside down by accident. 
- Everything was scaled up 120% so the bits are easy to pick up an manipulate by all hands big and small. 
- The problems have been redesigned to use less material but maintain the necessary rigidity
- I've moved the number labels to the front to make them much more clear. 
- I've rearranged some of the problems so the difficulty increases more progressively at first.
- Thanks to the brilliant solver program by [Darci Peoples](https://darcipeoples.com/), I've changed many of the problems to have fewer solutions, making certain problems significantly more challenging!
- The updated solution guide PDF is attached, including problems 001-050

**_Printing Guidelines_**
- bits : 0.16mm layer height, 2-3 walls, 0.4mm nozzle, 15% infill
- problems : 0.16-0.25mm layer height, 1 wall, 100% infill; *printing the first layer with one wall can help with bed adhesion of the number labels*
- board : 0.16mm layer height, 2-3 walls, 15% infill; *for better grid visibility swap filaments at 1.5mm layer height
- cover : _'wLogo'_ version is two parts. Print combined using a multicolor printer or using [Multipass Multicolor Printing](https://makeanything.design/multipass-multicolor/) technique for single extruders.
- board_premium : filament swap at 8.2mm height for better grid visibility. _'TPUgrip'_ can be glued to the bottom for a nonslip board, printed with TPU 95a or similar flexible filament. Use [E6000](https://amzn.to/3UIOdso) adhesive or similar.
- case : use _'size20'_  together with _'Sleeve_Wide'_ or _'size30'_ with _'Sleeve_Tall'_. Wide sleeve holds 21 or 20 problems with the Handle, Tall sleeve holds 27 or 26 problems with Handle. Handle can be used loose (slide in from the bottom of the sleeve) or glued into place.

SKEWBITS v2.0 Puzzle Game // Premium Set + Problems 001-010

bit_A_red.stl

The Tsugite Cube has reached unprecedented extremities with this 4x4 version of the confounding puzzle cube series. 

Join all 31 pieces in the correct order and orientation to create a continuous loop in the form of a solid 4x4 cube. The Kawai Tsugite joint connects in 3 different orientations, so this isn't your average packing puzzle! 

As a helpful hint, no like colors will touch when printed in 6 colors... Consider that a part of the puzzle since it's already difficult enough, but if you feel like an even more extreme challenge, you can print it all in one color.

This download also includes a flashy Special Edition 4x4 Stand, along with the default cube stand. There is also an STL of the entire assembled puzzle if you need help solving, or check out my full [Solution Video on YouTube](https://youtu.be/yZwMSwlxIy0).

---

**_Printing Guidelines_**

Print at 0.16mm layer height with 3 shells and 0% infill, 5 top and 5 bottom solid layers. No supports required! The puzzle parts are divided into 6 groups, where no like colors will be touching for the solved puzzle. You can split the models into parts within your slicer if you wish to print/color separately, or need to rearrange parts for whatever reason.

The SE_Stand is a somewhat difficult print without supports. I used fuzzy skin with 0.2mm thickness and point distance to hide any wobble artifacts near the top and as a general aesthetic. I printed with 4 shells, 0 top layers, and 15% lightning infill. You may also need a brim or minimal supports to improve printability. The basic stand is much easier to print!

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!

Please see the linked video for assembly instructions.

**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

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

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.
