This is a replacement cap for one side of the weights on the 55lb NordicTrack dumbell set. It should also work on dumbells from other brands that look identical.

I would recommend printing it vertical, so that the print lines are horizontal to the stress placed on the plastic peice.

I havn't tried printing with 100% infil, but I'm sure it would help the strength and longetevity of the print.
