This version of GearBin™, which I have created at the request of many users, has an open frame allowing you to see the gears and push mechanism.  Otherwise, the GearBin is and functions the same.  The internal parts are all the same as the original GearBin.  

The housing of this Open Frame Edition can be used in 2 ways as follows:

With the front and sides open (no covering).  In this scenario, an additional part is required to retain the push-push mechanism’s indexing arm which was previously contained by the front housing.  
With the front and sides covered with clear or translucent panels.  I have included printable panels which (in my experience) are translucent but because the gears sit right up next to the panels they are relatively visible.  Or you could use the panel STLs to fabricate the panels in a clear material.

GearBin is a fully 3D printable mini trash bin with a unique mechanical twist. Designed for use with biodegradable dog waste/poop bags as liners, it’s the ideal solution for food scraps, backyard clean-up, BBQ prep, or anywhere you want a tidy, compact bin that works smarter - even your desk.

I chose to use biodegradable dog waste/poop bags for this because they are a fraction of the cost of biodegradable kitchen bags and smaller so you can discard them more frequently at a lower cost.  

**Ideal For**
Office or desk
Kitchen countertops
Outdoor prep areas and BBQ stations
Composting and daily food waste
Eco-conscious homes using dog poop bags for liners

**Features**

✅ Gear-Driven Push Lid: Open the lid with a simple press on the front bar—no electronics, just clean, mechanical magic.
✅ Folding Liner Frame: The innovative push-push mechanism folds the bag frame inwards for easy loading and unloading of liners. Holds standard dog poop bags securely.
✅ 100% Snap-Fit Assembly: No glue, screws, or springs. Just print, snap together, and you're ready to go.
✅ Optional Bucket Insert: Use with or without a removable bucket insert (included) to catch leaks and assist with liner removal.

Make trash collection cleaner, smarter, and more efficient—with GearBin™, the mini bin that thinks big.

**Assembly Notes**
I will have an assembly instruction video posted shortly.

**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.

2025-05-26 Model Updated (revisions 1v00a3)
I have revised the Lid and Lifters so that the lid lifts up vertically before rotating.  This was the original intent but I realized after posting it I had slipped away from that.  
I have also added a wall mount bracket.  And, in order for the GearBin to attach to the wall mount, a new Top Housing has been posted that has mounting holes in the back.  
Lastly, if you were one of the first few people to download the model, I have also posted revised versions of the Compliant Index, this newer one operates the push push mechanism more consistently.

**What Makes It Special**
**Self-Closing Iris Lid** – When you place your beverage can inside, the lid closes around it. Press down on the DrinkColder top and the lid opens as your drink rises up. It’s all mechanical.
**Desktop Engineering Toy** – Beyond just function, it’s fun. Watch people’s faces as they figure it out.  
**Print-Perfect Design** – Designed to print support-free, with one built-in removable brim to ensure successful printing.
Great Conversation Piece – On your BBQ table, patio, or even your office desk.

**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.

**20250617: **

1. I found that where the Top Walls (111) part was originally printed inverted, if you get any curling on your bed it does not sit perfectly with the Top Cap (101).  So I now recommend printing it non-inverted.  Therefore I have changed the brim location, modified the orientation in the STL and revised the part.  The new part is version 1v00a3 (the original was 1v00a).  If you are printing this model for the first time or you printed it successfully already you can ignore this. 


**Top Walls         Filename                                                           Status**
Original            DrinkColder 1v00a1 111 Top Walls         Removed
Revised            DrinkColder 1v00a3 111 Top Walls        Replaces 1v00a1

2. I discovered that the upright elements of the Base (301) could snap off relatively easily while inserting the Posts and Gears so I have strengthened it.  If you are printing this model for the first time or you printed it successfully already you can ignore this. 

**Base                   Filename                                                          Status**
Original             DrinkColder 1v00a1 301 Base              Removed
Revised             DrinkColder 1v00a3 301 Base             Replaces 1v00a1

3. While working on a Tallboy (16oz) can version, I realized that I could make the top assembly a little (10mm) shorter.  Doing so changes nothing about how the DrinkColder operates but it makes it smaller overall, and therefore faster to print and with less material.  So it is a great alternative.  If you would like to use this new shorter design you need to print the new Top Walls (112) and also a new shorter Ring Gear (212). I am not sure how to best present that so I am leaving both sets of parts (the original and the shorter ones) in the posting.  All other parts remain the same.  

**Top Walls         Filename                                                           Status**
Original           DrinkColder 1v00a1 111 Top Walls         Taller Version 
New Part         DrinkColder 1v00a3 112 Top Walls        Shorter alternative to 111

**Ring Gear         Filename                                                           Status**
Original            DrinkColder 1v00a1 211 Ring Gear        Taller Version (pairs with 111)
New Part         DrinkColder 1v00a3 212 Ring Gear        Shorter alt. to 211 (pairs with 211)

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.
