Solar Filter

Solar Filter Frame For 10" Dobsonian Designed to fit an Apertura AD10, which is a 10" dobsonian reflector, and to utilize Baader's AstroSolar Safety Film 5.0 in a 200mm x 290mm sheet. I made it to fit the internal diameter of the tube, which was about 290mm. The outside diameter of the filter sleeve is 289mm. The outside diamter of the frame is 350mm, and internal diamter is 190mm. You will need to print 4 of each file and offset the top frame by 45 degrees relative to the bottom frame when bolting them together. I printed with only a 15% infill and 0.3 mm layer height for speed. It worked, but was not very strong. If you have the time, I suggest using a higher infill percentage. I used a highly modified ender 3 pro to print. You will need a print area of similar size to mine, 235mm x 235mm Materials i used: 16pcs - m4x12mm bolts 32pcs - m4 washers 16pcs - m4 nuts double sided tape for securing the solar film Update 7/21/19: As shown in one of the pics, i did use a 3d pen to weld parts together in 4 places underneath the filter frame. This isnt required if you dont have one, but it does help with rigidity.
