100W COB LED mounting plates w/ 5mm holes

thingiverse

I have not tested these personally yet as the libraries are all closed due to COVID, but plan to and will report/update this well done. Just figured would upload and contribute now. These specs are meant to hold COBS with these dimensions - 100w - https://www.ebay.com/itm/High-Power-LED-Lamp-Light-COB-SMD-Bulb-Chip-DIY-3W-10W-20W-50W-100W-3V-36V/272421124788?ssPageName=STRK%3AMEBIDX%3AIT&var=571399829650&_trksid=p2060353.m2749.l2649 - I am personally using these brackets to firmly hold the COBS against my 240mm x 40mm x 12mm water cooling blocks. I am also uploading a custom mount to hold said cooling blocks to whatever mount you'd use, ideally aluminum but I am using wood because that's all I can afford. Though I think the way I designed these blocks it would be enough to hold the COBS and mount the blocks with COBS using the second row to whatever surface, I'd rather have it overkill than underkill for modularity and such. Let me know if you have any questions. They are designed to sit on the far outside white framing of the LED and not obstruct light output. As you'll notice one is a plain block, one is a little more fancy with an attempt at a reflective element, and the third is my hardest one which I hope will be the best and most desirable design as it looks nicest and should have the most favorable reflective quality.
