snap together LED strip bar for SCteacher's CR10 Light Bracket

thingiverse

I saw SCteacher's elegantly designed CR10 LED Light Bracket arms (https://www.thingiverse.com/thing:2521046) and gave myself a challenge. Without modifying the original arm could I design and print snap together complementary parts that would allow me to: a) use excess 10mm wide LED strip I had from another project b) experiment with ABS filament c) use LM2596 buck converter boards to power said LED strips. These can be found on ebay for ~ $1.50ea. d) power the whole thing from the 3D printer's internal 24V power supply Here it is. Took 5 iterations to get the tolerancing right but I think it turned out pretty nice. The 260mm long bar fits neatly into SCteacher's arm with a satisfying snap. I gave generous play for LED strip variance. The buck converter sits right on top with short wires to power the LEDs. With 24V in at 510mA and 12V out (for 2x 260mm strips) the LM2596 stays cool enough at this constant 12W power. And now I know how to design clip ;-) Print 1 bar and 2 clips, plus SCteacher's 2 arms for the whole kit. Still to do: permanently wire the dcdc into the CR10's internal 24V PSU. Thinking of replacing the side mounted ribbon cable with a drag-chain arrangement. Will do these mods together.
