Dumbbell Nut [with retaining ring]

Yes, there are already some dumbbell-nuts out there. But they were all missing the possibility to add an additional retaining ring. So i've made this one, which fits a standard D=30mm dumbbell-bar.

Also, this model is as close to the original as possible.

Technical Data:

• fits a D=30mm dumbbel-bar
• thread pitch = 7,6mm

Print Settings i've used:

For the dumbbell-nut:

• 30% infill
• no supports
• PLA+

For the retaining ring:

• 100% infill
• TPU
