Tamron 28-75mm Bahtinov Mask

thingiverse

This Bahtinov mask will pop right on to your Tamron lens as long as it is threaded for 67mm filters. I designed it around 75mm and f/3.2, though it should work in other focal lengths and apertures. My attached photo shows the lens focused on Jupiter with the mask installed. You can print this fairly quick, i used my "speed" settings and finished the print at 0.2mm in 30min. You can probably bump the layer height to 0.3mm, but i have not tested it yet. Supports required for the outside edge lip so it does not droop down.
