This looks cool. I designed a typing aid with similar intention when recovering from palsy wrist-drop due to a damaged right hand radial nerve. It was based on curtain rail eyelets for each finger, loosely laced to a table vice-mounted rod, traversing my keyboard a few inches above my ill hand, with hobbycraft 2mm clothing elastic. It worked a treat after I got the tension about right, though the injury took more than 3 months for my 50+ year old body to get reasonable recovery from. I have since fully regained all my touch typing skills that I had before the accident with no further need for the jig, so I know this kind of thing actually works. I have since met people with similar injuries who unfortunately have never recovered, even after years. If you have difficulty finding suitable springs for this item, maybe some similar clothing elastic from hobbycraft would work for you in this rig also.

excellent work. Congratulations¡¡

Yo Thingaverse! the ZIP files are messed up!!!

The individual files work fine.

I'll let Thingiverse know. Thank you Calvin!

Any way to stop them?

Thank you for letting me know!

The people at Trikolaa are not selling the files for the hand. They are selling the printed product for the people who do not have access to a 3D printer.

cool to see other people designing similar designs as my old hANDi :)

I really like your design.. I made my design when I just started to learn a new software.. so not every part is optimized for 3d printing.. and I have a lot of parts..

big thumbs up for your design :)

That's an awesome story- thanks for sharing! The two devices are very similar.

Great design! One question, Is there a reason why you had it print the fingerclips standing up? If you print out the fingerclips so the circle part of the cylinder is on the floor, then you have less extra waste material to remove.

Hi Praterma2,

You are correct. It was my intention to print the fingertips in the way you described. The stl may not load in this orientation, but my instructions indicate to print with the slot side down so there is no overhang.

Thanks for the question!

wow what a great idea would have been very usefull after my surgery if they had this when i was a kid.
thanks for sharing

Oops - I guess I really don't know my right hand from my left hand. I meant to say...I would really like to make an Aquahand for the right hand. (.sldprt files would be awesome.)



Hi Mike!

I've uploaded sldprt. files labeled cuff XL and cuff small (wrist piece) and firehand (hand piece). If you keep the bolt cuts (on cuff and hand) and screw cuts (on cuff) alone, you should be able to use the same hooks and bolts. The finger tips should be the same.

Please let me know if you need help! I'm happy to investigate any issues should they arise.


p.s. Under "I Made It" a Thingiverse member used rubber bands instead of springs. Harder to measure strength, but easier to find around the house!

Great design. I would like to make on for the left hand for a stroke patient. Could you provide the CAD files (.prt, etc) so that I can mirror it?



Hi Mike,

The Aquahand shown above is for the left hand. I have SolidWorks files (.sldprt) if you still want them.


Check out the Wolverine! This awesome device facilitates the tenodesis motion for people with flaccid muscle tone.

Be sure to check out the Spiderhand! This is my teammate's exoskeleton for stroke victims with flaccid muscle tone.
