I bonded the Aluminum channel to the printed corner pieces with 5 minute epoxy.

To make it you need to print:

5 x Star Inner
5 x Star Inner Cover
1 x Star Outer Cover With Cut Out
4 x Star Outer Cover
1 x Star Outer loop and wire slot (I used this as the top piece - you can open the wire slot as require to suite your wire gauge once printed)
2 x Star Outer with Loop (I used these as the bottom 2 corners)
2 x Star Outer

I used 33 cm pieces of track and 35 cm strips of LED, I would not go too much longer than this without extra supports as I think it would become to flexible, you could easily user shorter sections of trac
