I wasn't very impressed with the publicly available files for 3D printed pushup bars so I decided to make my own. The main benefits of this model over other available models is that this is printed in 3 pieces (per bar, 2 bars) rather than 1 piece. This means no supports are required, no sanding or filing is required, and no plastic is wasted. Glue is recommended but not required for function.

Features:
-No supports
-Overbuilt, not going to snap mid use, half inch of plastic at weakest point
-Grip is the same diameter as a barbell (28.5mm) I chose this diameter because I like barbell lifts and figure I might as well be practicing barbell-grip mind-muscle connection while i'm doing pushups rather than use some arbitrary grip diameter that translates to barbell lifts less
-5.5 inch grip, large enough for anyone other than Shaq
-4 inch height. Keeps hands off potentially dirty ground and allows a deeper pump than conventional pushups
-572 grams at 50% infill. About as cheap in material/electricity cost as the cheapest equivalent on Amazon.com except this one is way more overbuilt and can be customized to the consumers desire. Consumer could even attempt 20% infill to save a lot of plastic if the consumer is a lighter weight person, or if they are confident in the strength of 20% infill.

Room for improvement (V2 will be posted in the future if I ever need another set):
-Save plastic on stand height. You would still get great depth but save plastic by taking 1 or 1.5 inches off the square shaped stand height
-Save plastic on the base width. Only purpose of that width is for balance and the current 6 inches are likely not required. 4 inches would probably be fine.
-Save plastic on neck of stands (part that inserts into handle). You could likely cut .5 inches or more off and still have the same function
-Change shape of neck to hexagon/triangle/square/non-circular shape. This would keep stands from flopping around even without the recommended glue. This would also insure that if the glue does fail, the bar still stays straight
-All in all could likely get the product down to 350 grams of plastic total which is pretty cheap in comparison to Amazon options that are far worse quality.
