I started this project a year ago, my ideia with was to make an easy modular system that could create different gates with the shapes and sizes.
Initially i made these to use old used Led strips that i had laying arround. If you don't have any of led strip i advice you these:
You can use any 5v powersupply, a powerbank, or even Lipo using one of these
2S-6S Lipo to USB Power Converter 5V 2A - https://bit.ly/2OwDzE2
All the gate parts are designed to 10mm Width led strip. You can you use non-waterproof or waterproof led strip. If you find that the waterproof led strip is difficult to pass through the 3dprinted parts, put WD40 in a napkin and softly pass it through the led strip to make it easier to insert in the 3d printed part.
With these parts you can make square, rectangular and hexagonal gates with the size you want. Just add the extension parts between connections.
Use "Corner Part", "Hexagon Part", "Extension60mm", "Extension120mm" and "Extension180mm"
You can link the similar gate shapes and create a tunel using the "Link+Part"
The "Feet part" allows you to easily put the gate on the vertical. This part also allows you to link and stack the gates using the 4 slots they have.
The Link_Xpart" its a smaller part that allows you to link and stack the gates using the 4 slots they have.
There is a "Link-Cube part" that you can use to create cube forms.
There are two "Gate Fixation Parts" to use with this part ( https://bit.ly/2P2YGuw ). My ideia here was to have a simple way to fix my gates to any super flat surface like glass, metal sheet and similiar using a powerfull suction cup.
I now have more than 12 single gates, 3 tunels, two cubes linked and all with Led strip. For all these gates i used 4x PLA Clear spools and lots os spool remains from other filaments for acessories. What can i say i like to play with whoops. ;)
Here is a small video where i use some of these gates!
