5/18/2024: There is a new, wider version of this design, and another version which will hold 3 watches, coming soon.  You can follow the progress on the next version on my blog.

This is a remix of my mini 1x2 Gridfinity Box for Stuff, and is intended to use as a watch case using a 1x2 Gridfinity Watch Holder which is linked below. Although this is designed as a 12U case, it will not fit bins, due to the way the lid is designed. It is specifically designed as a watch case. Although there is only a gasket version, it will also work without a gasket. The gasket will not make it water tight, since there are too many factors that go into a water tight print. If you have any suggestions on how to make a more water resistant gasket, please let me know.  Additionally, this watch case may look rugged, but please do not put your watch in it, and expect that it will keep it safe if it's rolled around.  It may also be worth lining the lid and sides with felt, since the gridfinity watch holders will not hold the watch 100% secure in the case, even if you install magnets.  

Update 5/18/2024 - Thanks to feedback on this model, I found that the STL for the latches was an older version which was too tight.  The 3MF had the correct model, so appears that the problem was only with the STL.  I updated the raw STL to a new file named “Gridfinity_LATCHES_L-V2.stl”.  Additionally, an updated (wider) version is coming soon, along with a 3 watch version.  You can follow progress on those designs here.

To use this as a watch holder, the following 1x2 Gridfinity Watch Holder is required:

I have included a 3MF with the files set up on plates, which should help with printing. There is a build guide on my blog with some tips on assembly. The instructions are for a case with more features, but it shows how to assemble the latches and hinges.

This case requires the following hardware:

(1) M3 x 12mm SHCS (these hold the latch “cleats” to the top of the case)
(1) M3 x 20mm SHCS (for the latch)
(2) M3 x 16mm SHCS or (1) M3 x 35mm SHCS (for the hinge)
(1) M3 x 30mm SHCS (for the latch)
(8) 6x2mm Cylinder Magnets - OPTIONAL
(SHCS = Socket Head Cap Screws)

PLA can be used for the boxes, but PETG is recommended for the latches. The gasket should be run in TPU (though it will still close without a gasket as well). A 3MF 5 plate profile is included. It uses the following settings:

• PLA for all parts but the latches (PETG) and gasket (TPU)
• 0.4mm X1 Carbon profile
• 3 Walls on most parts
• Arachne wall generator
• inner/outer/inner for the wall ordering
• 12% 3D Honeycomb infill on most parts, with 100% on the latches and gasket.
• No Supports
• Textured PEI build plate

AMS is not required, but here is how it is set up in the profile:
 

1 = PETG- Orange
2 = PLA - White
3 = PLA - Dark Blue
4 = PLA - Gray
5 = TPU - Black (this is the non-AMS spool on the back)

There is a blank label included. You can add your own text to this label using the text tool in the slicer. There is also a label designed to be used with 12mm Brother P-Touch (or similar) labels.

TPU can stick very well to bare textured PEI, and become difficult to remove. Therefore I recommend that you test that your printer can run TPU without issues first. Although the 3MF is set up for a textured PEI plate, please use a smooth plate if possible for the TPU gasket, and apply glue as a release agent.

To install the gasket, I used the cap of a sharpie to press the TPU gasket into place. The gasket is not symmetrical, so make sure to verify the position before installing it Start by pressing in the middle of the gasket along all 4 sides, then once it's set in position, press in the corners. The last pic shows the gasket install, which is much easier with the wider gasket this version has.

2. 1x1, 1x2 (3 Compartment) and 1x4 (6Compartment) bins with lids (6U) - version 2.1
3. 1x2, 1x3, 1x4 (6U, 9U and 12U) Lidded Bin for Stuff with Latch Version 2.0
4. 2x2, 2x3, 2x4 (6U, 9U and 12U) Lidded Bin for Stuff with Latch Version 2.0
5. 3x3, 3x4 (6U, 9U and 12U) Lidded Bin for Stuff with Latch Version 2.0
