1" Threaded Dumbbell to 2" Bar & More Parts
grabcad
I recommend printing the "Universal_No_Thread" variant of adapter as it is the most beefed up and only surviving member of this model in my gym.*old*There are currently 4 parts in this set.The blue and red parts are threaded adapters to go from 1" threaded dumbbell rods to 2" normal barbell weights. I made this because I have tons of 2" weights but not enough 1" ones.White part is just a locking nut for the 1" threaded dumbbell rod.All three are very easy to print. Print them the logical way rather than the default stl orientation. Currently the adapters threading appears to be designed by a 8 year old in sketchup but im working on it.
