M38A2 100 pound practice bomb
pinshape
This is a 60.86 mm diameter by 352.49 mm high model of the M38A2 100 pound inert practice bomb, meticulously crafted with precision. It was filled with sand and sometimes a small marker explosive then used during target practice in the forties and fifties to hone military skills. The originals were 48 inches long with a 9 inch diameter, but this scaled-down version is designed for easier printing on an FDM machine. To achieve quarter scale, simply resize it to 304 mm high, which is roughly .862 of its original height. One of the assembly pegs serves as both a support during printing and secures the tail assembly in place, cleverly hidden under the tail assembly. After printing, assemble the parts, add eyelets, and finish as desired. While supports are not strictly necessary, turning them on for the underside of the fins and between the peg and tail assembly is highly recommended to ensure a smooth printing process. Post-Printing The nose cone is carefully positioned on top of the body peg, aligning the hanger places perfectly in the right spot. The peg that prints under the fins plays a crucial role in securing the tail to the body, making it an essential part of the assembly. Don't bother downloading the "bombs away" STL file; I simply wanted to see how they would look in formation using ThingView. How I Designed This I created this model in SketchUp with meticulous attention to detail and a focus on functionality.
