Hand Grip Strengthener

Important Note: Assembly Requires Super Glue (Or bonding). It will press fit together but won't hold during use.

This is a little assembly I created some time ago after learning how to loft a handle grip in CAD. I wanted to create a little hand grip strengthener to see if it could be functional. The spring has little thin supports built into the model that have to be clipped out later.

I printed everything using Prusament PETG at 0.3 mm layer heights (I think, it's been a while). This seven (7) piece assembly requires super glue to bring it all together. The only parts that require supports are the little transitional pieces that go from handles to spring hubs.

The resistance is mild at best. Well suited for elderly grandparents and such. I plan to add a middle rod to the assembly in an effort to strengthen it up…stay tuned.
