SIDE BRACKET - TOPOLOGY OPTIMIZE

TOPOLOGY OPTIMIZED SIDE BRACKET. The gyms are closed here in South Africa so I set out to make my own pull-up bar. DESIGN INTENT: -This bracket is designed to support a cantilever beam holding a pull up bar. -The cantilever beam is already structurally secure due to the wall mount wood extending below the cantilever. However, I would like to alleviate the load on the screws attaching the beam to the wall mount. -Plus why not over-engineer something... note: -I am currently running several studies on different types of bracket shapes and attachment locations to support the pull up bar so this is one of several uploads. -When I print these I will re-update the post with photos if the part survived a static load test. STRUCTURAL DESIGN: -The load is transferred from the beam to the brackets by a through bolt (see pictures) -Each bracket is simulated with ABS plastic and a factor of safety of 2 to hold 31kg or 70lbs. In theory this means the bracket will fail at twice the load. -Actual results will vary with print orientation/settings along with I only have PLA + filament. Bounding Box (Dimensions): Length: 2.8cm Width: 13.8cm Height: 15.8cm
