"Guided Hands" mobility aid

This is my version of the "Guided Hands" device, which assists people with fine motor skill difficulties in using touchscreen devices, writing implements or anything else they may otherwise struggle to manipulate.

Parts list:

Baseplate:

Any suitable flat material can be used for the baseplate.  I have nominally based the design around a 400x400mm baseplate but any size can be used as needed, the only other part that needs changing is the length of the rods.

Hardware:

3off 10x400mm linear rods (lengths subject to the size of baseplate you are using)

6off LM10UU linear bearings

6off M4 grub screws

8off M4x25 countersunk bolts

1off M8x10 shoulder bolt

1off M6x25 thumb screw

1off 1/4-20 threaded flexible arm

Printed Parts:

One or more of these can be printed based on the needs of the user in terms of hand position, grip etc

Feel free to create remixes or additions for any changes or other accessories/grip styles that may be of use.  If you have a helpful mod, I can also add it to this model if you message me.

I have included STEP and f3d files for anyone wishing to make changes or additions.
