Some things are small and fragile enough that they cannot be held or touched by even the steadiest of hands. Such cases call for a micromanipulator, and [BYU CMR]’s DIY micromanipulator design can be 3D printed and assembled with the help of some common hardware, and a little CA glue.
You may recall an ultra-tiny Nerf-like blaster recently; clearly such a tiny mechanical device cannot be handled directly, yet needed to be loaded and have its trigger pressed. A micromanipulator is exactly the tool for such a job. This design is in fact the very same one used to move and manipulate that tiny blaster at a microscopic level.
The design doesn’t include any end effectors — those depend on one’s application — but there is a mount point for them and the manipulator can effectively move it in X, Y, and Z axes by turning three different knobs. In addition, because the structural parts can be 3D printed and the hardware is just some common nuts and screws, it’s remarkably economical which is always a welcome thing for a workshop.

Ah, ego manipulator.
You sir win the Internet today.
Agree
Stop stoking his ego already, sheesh. :)
You must be a pelvis extreme sports guy. Wish you always two finger thick lube on your work outs.
But go and learn how to dance, than you can change to tandem sports.
And codpieces to without embarrassing them.
So this is how my wife deals with me.
The thing is, we always move. Our heartbeat let our body move with 1 Hertz. Had to delevoped a stabilizer years ago and firstly i had to learn the basics of the human Body and motion.
Came for PP jokes , wasn’t disapointed
56 tpi screws? That’s going to move 453.6 um per turn of a screw. Yuck!
I would have used a compliant mechanism and metric differential screws that would easily get 100 um per rev.
Wonderful! Let’s see the link.
This page shows how a differential screw works and how to make one: https://drmrehorst.blogspot.com/2020/03/a-new-z-axis-optical-endstop-design-for.html
I recall seeing at least a couple HAD stories on compliant mechanisms in the last year or so. Combining the two is a no-brainer.
