The StashCan is an imitation soda can with a programmable combination lock on the bottom of the can and a sequential puzzle lid which prevents unauthorized access to the can's contents.  Super fun and super detailed.  This new version 2.1 has updated files, instructions and support for AMS so that the combination on the bottom of the can is more visible.  But it also prints well without an AMS.  

It is 100% printable, and no hardware fasteners or adhesives required.  

It is a fun, hide-in-plain-sight storage solution with added functionality thanks to the combination lock. While it is not entirely secure due to its portability and plastic material, it provides an enjoyable and challenging experience.  It is going to likely be the most complex thing you have ever printed.

This is an advanced model with many details, so please refer to the documentation on my blog at https://www.logicalplanet.com/ and watch the accompanying video before attempting this print.

There are many boxes around us that hold objects of various shapes and sizes. In particular, there are a lot of small things related to work on the desk, and there are a lot of storage (Box) to put them in. But it's hard to find Storage(Box) with fun and humor. So Fab365 is designing Storage (Boxes) that are fun to see and use. As a series, this time, I designed a storage (Box) in the form of a bank vault.

The door of the bank vault is designed with several cogs connected to it. Therefore, the friction between the parts is high and the gears may not move well. Therefore, we recommend that you do the following after printing is complete.

1) First, carefully shake and move the cog wheels to drop the parts so that they do not stick. It is better to use pliers with a tapered tip.

2) Then, insert the handle and turn it to check if the gears or locking bolts move well.

3) If the locking and opening function does not work well because it does not move well, you can drop the sewing machine oil or lube between each part to make it move smoothly. Sewing oil or lube is easily available, and sometimes, when you purchase a 3D printer, it is included with several tools.

4) When it is confirmed that various parts move well, press the front part with the safe door to the back body of the safe and connect it.

5) Finally, attach the handle to the shape of the protrusion in the center of the door and attach it with glue.

Biggest part size X : 82mm, Y : 82mm, Z : 63mm

I made a British Police box as a follow-up to the public phone booth I had built before. British Police box is one of the symbols of British culture. Especially, it became more widely known as "Doctor Who", which was used as a transcendental construction device in science fiction drama.
Unlike the public telephone booth that we had already built, this time we adopted the folding method. You can open and close the door, unlike the actual Police box, you can open both doors. And you can open and close a small door. These doors are designed to open outward but not inward.

When printing and folding, use a heat gun or a hair dryer to smoothly fold it without breaking it.

It can be used as an interior accessory, or as a place to put small items on the desk.

20240509 update:  I have a new version 2.0 of this design with a programmable combination lock in the base.  Check it out at...
https://than.gs/m/1060354

----------------------------------------------------------------
This 3D printable soda can replica is a fun hiding spot with a secret combination opening.  Kind of a hide-in-plain-sight toy safe.  Super fun for kids or those like me who are kids at heart.

The top opens only when a special sequence of actions is applied (see the attached image with instructions).  

Obviously, it is not a great safe as someone can just walk away with it. But in terms of fun for those who want a hiding spot for something small, it is pretty good.

All the components of the design are assembled as shown in the image (and please watch the video too).  No fasteners or adhesives are required.  But I do recommend applying some lubricant as described in the video.

I also include a plain lid that does not lock. It is just a screw-on lid.  If you print that make sure to use a low infill like 10 or 20%.

100% printed - no hardware, fasteners, or adhesives required.  

Printing

Material: Any material.

My Setup:
Nozzle = 0.4mm

My Settings:
Layer height = 0.2mm
Line width = 0.40mm
Wall count = 4 (1.6mm)

Designed to print without support except for the lid which has support designed in. So do not add support.

Commercial Licensing is available through my logicalplanet Memberships here on Thangs.  I will customize and provide commercial support to members on request.

I am committed to helping everyone get great print results to the extent I can so please contact me if you are having issues I enjoy trying to help resolve those challenges.  I welcome requests, suggestions and ideas to help make this and all my products better.  Please send me a message any time.
