Dust caps for LED bulbs NA1 NA2 - optimised to minimise supports

thingiverse

These are remixes of Russ's awesome extended dust caps for 1991-2001. There are 2 versions: Vented: These are a remix of Russ's vented dust caps, modified to only need supports for the 3 small tabs. Also eliminated the stress concentrations at the corner of the inside of the cup and one of the corners of the flange. Print oriented like a cup. This cuts your print time by >50% - Prusa MK3s from 6:45 to under 3 hours. Unvented: I made these for those who don't want vents in the caps. Boslla & Vleds state that venting the caps is unnecessary and can let dust get into the area behind the reflectors. Also optimised to not require supports except for the 3 small tabs. The tabs are also reinforced with small sections behind. I recommend printing these sections solid, but the rest can be printed with gyroid at 10% infill. NOTE: The measurements are different for these caps from Russ's original way of measuring. The measurement in the file name is the interior depth in mm, measured from the gasket surface on the headlight assembly. (Russ's measurement included the portion with the tabs on it (12 mm) and the thickness of the back (2 mm) so are 14 mm longer. Simply hold your connector on top of the bulb fins and measure from the gasket surface as shown in the photo, which is a cross section of the dust cap that was printed to show the 3D geometry.
