More stable tablet stand

I had some issues with wobble in general so i made some changes.

• the baseplate is now 4mm thicker (to make it not flex as mutch)
• the “bracket” is adjusted for the thicker baseplate
• i made the “base arm” 2cm shorter (also for stability)

added some filament in the gap of the baseplate, i don't know if that is there for this reason, i just think that it is soooo cool!

Thats all, it is so much more stable now! i upload all the files and arrange them the same as the original for the sake of simplicity :)

Read the original description too!
