PLUTO tablet vertical stand

I had a problem with standard tablet holder for desks: they occupied too much space. So I designed this tablet stand that moves vertically, it doesn&#39;t occupy more than its base space.Then I wanted to be operable with only one hand, without the need of unscrewing things around to move the tablet 2 cm more. So PLUTO is born. Inspired by Braun and Ikea designs. ROTATE THE RING AT THE BOTTOM TO LIFT AND LOWER THE STAND!It&#39;s height adjust from table level to higher than a laptop screen, to use the tablet behind the laptop (as second screen).You can also use it for external display and bigger tablet (I use it also with Ipad pro 13&#34;) You can print it in PETG and PLA (profile in PLA). Use lubricant for the leadscrew and gear if you want. Assembly it&#39;s pretty easy:ATTENTION: before everything, try the lead screw and the holder, be sure they slide perfectly.1.Install the column and the top base:2. Install the bearing and gear (gear must be in the same direction!):</fig
