Bowflex Selecttech 552 Series 2 Discs 2, 3, 4 and 5

thingiverse

I broke three discs on my Bowflex Selecttech 552 Series 2 (White Numbers) dumbbell accidentally. I saw how much the replacements for these discs cost, so I decided to make my own. I printed these disc with PLA, but of course they'll be more durable with ABS. I don't have ABS, but since printing the disc with PLA, they are working great for me and have not broke after much use. Be very careful when disassembling the dumbbell. There are washers, springs and ball bearings in the dumbbell which you will lose if your not careful. When you take the dumbbell off the base and when you put it back on the base, make sure the dumbbell is set to 5 on both sides. Press the little button down on each side of the dumbbell to move the selector manually when the dumbbell is off the base, in order to move the dumbbell back to 5 before putting it back on the base and in the weights.
