ULTIMATE Workout Bench Bowflex 3.1 Modification

thingiverse

Apr 13, 2020 - I have updated the designs to account for a change by Boxflex, it has been confirmed to work. The newer version also includes a lot more adjustment for the back. The seat adjustment can still be improved and that will be a future project. https://youtu.be/mb6xCadXje8 I created these parts because I was not completely satisfied with the amount of adjustment on my Bow-flex 3.1 bench. I have tested 3D print strength in the past, and with a lesser infill, an ABS print can handle beyond 1000 lbs before breaking. The loading applied here is evenly distributed over a moderate surface area, this means there should be no issue with strength. I do not recommend PLA for these prints. I print very slowly with the ANET A8 to minimize vibration, so the total print time was approx 20hrs. You may be able to print this in 12-15 hours. The back spacer has an option to house two 1/2" x 1/8" rare earth disk magnets while printing. I have not tested this yet, however there is a small amount of tolerance built in to allow for success on many printers.
