Summary

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.

Can I see the dimensions for the design please? At least the hole size for the finger and the thickness screws.

So brilliant! Great job with this design. I've had this on my list of things to design for too long. And you DID IT! Really nicely done. Can't wait to print one and try it...

Cool! Have fun!

Looks nice yes, but you never wrote this with that "thing". It is not possible to write with kind of that nice looking.

Super cool but there is not cap

It's the Gom Jabbar in Dune story !!! ;o)

Now I can lift my middle finger without a trouble...

oh,i had made one,but snap joint can not complete occlusion,some material have to cut of, can you help me?

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.

Thanks for the suggestion.

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

can u plz make 1 Solo Finger Pen that fit u so i can copy it plz )=

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!

What scale and unit of measurement are these supposed to be printed in?
