A drink cooler… that opens and closes by itself? Yes — and it’s awesome.

The DrinkColder is a functional, mechanical, and totally novel 3D-printable drink holder and passive cooler designed to automatically open and close based on the weight of your beverage. No motors, no springs — just smart geometry, precision balance, and gear-driven magic.

An IceCozy freezer pack for the DrinkColder is available here... [https://than.gs/m/1364094](https://than.gs/m/1364094)

**Why You’ll Love It**
This is more than a drink holder — it’s a conversation starter, a mini engineering demo, and a satisfying desktop toy all in one. Whether you’re hosting a backyard BBQ or just need a cool way to store your LaCroix at work, DrinkColder delivers form, function, and fun.

**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)

When I saw the Strong TPU Strap by Turbopstros (https://www.printables.com/model/1451354-strong-tpu-strap-parametric), I had a vision. That's where this bag comes in. I created my version of the TPU strap which is in this file. 
Join me in creating a stunning, unique tote bag with this 3D-printed kit! This project combines 60 PLA flat rings with flexible TPU straps and a sturdy 3D-printed bag base to form a chic, interwoven design. The final product is a durable and stylish bag, perfect for carrying your essentials. If you choose, you can add a lined pouch for added privacy.

This design is a great way to blend 3D printing with crafting, using simple leather rivets to hold the beautiful braided structure in place.

Assembly Instructions (Braiding and Riveting)
Materials Needed:

60 x PLA Flat Rings (Included in file)
1 x Bag Base (Included in file) printed with fuzzy skin
TPU Strips (Print 4 of the included TPU strip file)
2 pieces @ 43" (Handle Strips)
5 pieces @ 25.5" (Horizontal Body Strips)
8 pieces @ 13" (Vertical Body Strips)
34 pairs of 6mm leather rivets

Tools: Hole punch, scissors, and rivet pliers (recommended for easier access).

Detailed Video Instruction: For a step-by-step visual guide, please check out the linked video instruction on my YouTube channel

Assembly Steps:

Prepare the Strips: Cut the 4 printed TPU strips into the lengths specified above for the handles, horizontal body, and vertical body strips.

Attach Handles and Vertical Strips to Base: Slide the 2 handles and the 8 13-inch strips into the slots around the bag base. Punch holes and attach these strips evenly around the perimeter of the bag base using a total of 24 leather rivets (12 pairs). Ensure the strips are secured.

Start the Braiding (Horizontal): See video.  After each round, you'll need to connect the 25.5 inch strip with a pair of rivet. 8 pairs on each side of the bag. 

Weave and Secure the Rings: Continue adding the PLA rings and weaving the horizontal strips, working your way up the bag. The rings should be held in place by the tension of the interwoven strips.

Secure Horizontal Strips: Once the main body is woven, secure the ends of the five horizontal strips to a vertical strip or the bag base using the remaining 12 leather rivets. The weaving action itself is the primary mechanism holding the bag together.

This is probably not the first clean/dirty dishwasher magnet you've seen, but ~it is the coolest~ this one doesn't contain death crystals! A simple, easy way to keep track of your dishwasher - as long as you remember to flip the sign you will no longer have to guess & inspect dishes to figure out if it was run. There is also a blank sign for you to add your own text! Check the attached YT video to see a quick tutorial on adding negative modifiers like text to a model!

**Dimensions**:  100 x 60 x 4 mm (~3.9 x 2.4 x .16 in)

**Weight**: ~19g + 1g waste

**Additional Items**: You will need 2x Magnets, sized ~20x5x2. You can find them [here on amazon](https://www.amazon.com/gp/product/B07Q6564FB/).
Note that tolerances are loose on these magnets so if one does not fit well just try another from the set. You may also try a little glue if you have any issue with them coming loose. 

___
**PRINTING**:
- Clean your build plate! "Flat" models like this are more likely to shrink and peel up. 
- Print from either side. I prefer design face down on a nice textured plate like the cryo plate
- Print with at least 5 bottom & top shell layers, 2-3 walls, 0-20% infill
- 3mf included with all three designs and a layer change added at z=1.2mm (layer 6 for .2mm layers)
