LED optics lens holder
thingiverse
Two versions of a holder for a 20mm lens for a 1W, 3W or 5W LED of the type in the pictures. It will hold the lens and LED in place onto your heatsink, with a little room for thermal paste/glue. The "...cut"-file is made to be kind of stackable. Made simple and printer friendly. These are the lenses i have bough: <a href="https://www.ebay.com/itm/10pcs-Led-lens-5-8-15-25-30-45-60-90-120-Degree-20mm-For-1w-3w-5w-High-Power-Led/251985306211?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20140107095009%26meid%3Db3cc6e6c80764f34834de01b2af5f8be%26pid%3D100040%26rk%3D3%26rkt%3D4%26mehot%3Dpp%26sd%3D252161082616&_trksid=p2046732.c100040.m2060">ebay lenses</a>
