ULA Bracket 2 Parts · 模型 257871
This is my design of the ULA Bracket. It is weight and 3D Printing optimized while there is barely no support material needed. I decided to make two instead of one part to reduce the weight and make support material not necessary for the bridge. The screw-surfaces of the lower and upper holes are placed near the wall to reduce the length of the screw which also reduces weight. Since there is a high stress (not above 4500 PSI) in the lower hole I recommend steel inserts after printing. I also added optimized relief grooves to reduce the notch effect. The minimum diameter around every hole is 4*D. The high resolution FEM Simulations show that the ultimate load of 600 lbf (300 per part) cause a maximum stress of 4430 PSI which is under the claimed 4500 PSI (don´t be confused of the comma („ , „) but in my country (in my software) we use this instead of a point („ . „). It is highly recommended to choose the build direction while printing as shown to reach higher strength. Facts: Weight = 0.134 lb (0.067 lb per part) Volume = 2.772 in^3 ( 1.386 in^3 per part) Thanks for the great challenge and good luck to everyone !
