hey i made a mount for some led strips i have each base module is 50mm long as that is how long the sections are in the strip i'm using i'm hoping it's fairly universal then i have some end caps that have a wiring hole in them both base module and endcap have spots to fit 9x2mm round magnets in them also a 3mm hole on each side to run string/elastic/wire through them to hold them together and make shaping them easier i have also made a quick diffuser that slides in the top slot for if you want that

UPDATE: added endcap with no wire hole and made diffuser v0.1 a little thinner to make it easier to slide in
