UPDATE: 3-19-17
New model files have been posted. They are now sized as millimeters. The previous models were posted as inches.

This mechanical finger can be a lot of fun to play with, but can possibly serve as prosthetic for someone with missing a thumb or other fingers. Additional parts needed: a basic flexible "BIC" pen insert. Four (4) M3 x 10mm screws with washers. Other small screws may be substituted.

Printer Brand:



MakerBot Replicator 2X










Support is a must. I have positioned models at an angle that has worked well for me.

I recommend 3 shells for wall thickness.


Some clean up will be needed, depending on the type of support used.

Good and beautiful design. Have not printed yet.
Maybe nice for my father. His right hand is bad now.
Screw-less design is better.
Thank You for sharing.

To all,

I have re-posted the model. It is now sized in millimeters.

It is the same model. The original was in inches.

Thank you for the comments.

All in all a good idea.
I did print it to fit my finger, but - i'm sorry to say - it is not easy to print and comes out much too clumsy and heavy.
A stiff single fingerpiece, printed without joints in a 'Voronoi'-style would be much better - print it standing up from the platform on a small raft and do not make it more than 4 or 5 layers in thickness with no infill - no need for supports - apart from the bottom up (you could design a break away part with one or two layers there). Less material, less printing time, less finishing, no screws and better wearable - no sweating in warm climate.

Hello petercb,

Thank you for sharing your thoughts. I do consider this to be a work-in-progress. With help from other designers like yourself, it can be refined to be easier to print and more efficient with materials.

Please do go forward with the changes that you've suggested. Be sure to post your version back here to Thingiverse for others to enjoy.

Regards, Bernie Solo

how long should this take to print

The author answered me and he told: "This model is created with "inch" units. Multiply by 25.4 to convert to millimeters. Let me know if this helps." So, in Cura scale to 25,4 .

Great design! thanks!!

Ok, thanks for the info!
