This model was inspired by @Contrapaul 's extremely popular design… Hexagon LED Light (Large) by Contrapaul | Download free STL model | Printables.com and by @AndyHuot_3193751 modular LED track system Duality LED Track System by Andy Huot Creations | Download STL model | Printables.com.

I wanted to create a hexagonal light for my garage that could be configured in any hexagonal pattern and be any size, in terms of the number of hexagons. I managed to create a model where the frame consists of just two main parts, plus a connector. And then the diffuser is one main part covering the side of the hexagon, plus two different types of joins for the different vertices.

Some key design features:

• The light can be assembled and will hold together without the need for any glue or screws. The diffuser part slides onto the frame and adds strength to the frame assembly
• There is space to run wires (down to 16 AWG) within the frame so that they do not protrude in any way
• A hanging assembly has been created to create a loop from which you can hang the light (this will be needed at multiple points). I used picture frame wire. There is an option to do this with an M4 insert, or without, if you do not have an easy way to use inserts.
• Because the back of the light is flat, this can also be flush mounted on the wall or the ceiling. For this I would recommend velcro strips with adhesive e.g. [https://a.co/d/hCCxSej](https://a.co/d/hCCxSej) 
• The two main frame components need to be printed with supports. However, the design ensures that the supports do not affect the visible parts of the frame, and they should be able to be removed fairly easily.
• This will work with up to 10mm width of LED strip - I used 8mm wide COB LED's
• This does not require a large bed 3d printer. The largest part, the diffuser,  is just 142.5mm.

Just a word of warning. If you want to create a reasonably large light, say using 10m of LED strip, you are looking at roughly:

25 x 3-way frame parts ~ approximately 25 hours 

27 x 2-way frame parts ~ approximately 22.5 hours

66 x frame connectors ~ approximately 5.5 hours

66 x diffuser parts ~ approximately 33 hours

25 x 3-way diffuser joins ~ approximately 4 hours and 10 minutes

27 x 2-way diffuser joins ~ approximately 6.5 hours

66 x 150mm lengths of LED strip

There is a lot of printing and a lot of soldering. I personally do not recommend using clips to connect the LED strips, as in my experience, they make far less reliable connections than soldering. 

I used PolyLite black ASA for the frame parts, although I am sure ABS, PETG or similar would be fine. PLA is unlikely to be strong enough.

I used Polylite clear Polycarbonate for the diffuser parts although again, clear ABS, PETG or similar should be okay. PC is particularly strong and therefore perhaps the best choice if you find the legs on the diffuser joins are breaking.

The diffuser parts should be printed face-down, otherwise, supports would be needed.

Another note of caution. Do not solder and stick all of your LED strips down before trying to add the diffuser parts.  You will not be able to slide on the diffuser part with the wires in the way. You have to solder two strips together, stick one down, slide on the diffuser, then stick down the second strip, and so forth.

Hopefully, the rest of the assembly is fairly self-evident from the photos provided
