Rectangle halo lamp

Current Version utilizes 20x20mm u-beams. I will add other dimensions soon.
Please share your builds and let me know if you need different dimensions or have other ideas to improve this design!

Printing
---------------------
I highly recommend printing all parts in transparent or white PETG or ASA. Especially on the mounting parts, transparent filament looks much nicer.


Construction
---------------------
To cut the u-beams to the desired length at an 45° angle at the end, you will need either a hack saw with some metal cutting blades and a cutting block of some sort or an adjustable chop saw. The power tool will produce much nicer cutting edges, but the manual saw will work just fine.

After you cut all u-beams to length you could connect all beams using the printed parts. Use superglue to mount the parts in each corner of your rectangle. Make sure the fit is tight and try to avoid gaps between the u-beams.

If you have bad cutting-edges you could use some filler.
