LED Light Bracket

I designed this LED light bar to provide a lot of light with a compact design while not being expensive. The COB LED's and power supply were purchased on AliExpress for under $6 USD (links are provided in the misc. notes section). The COB LED's are on a bracketed adjustable mount. The light bar bracket is held on the 2020 frame with a bolt and nut that slides into the notch on the 2020 aluminum frame. All parts are printed with ABS. I chose ABS as it offers better heat resistance because COB LED's do get warm and strength because the bolt and nuts are under stress. I removed the frame on the COB LED's to aid in heat dissipation and to minimize overall form factor. The pictures show my old style wing nuts and bolts. The files attached are the upgraded version for better aesthetics and fit. This project took some time to design as I wanted to make all the bolts and nuts from plastic, which is a lot harder than i anticipated. I am new to designing and printing so I welcome constr
