I 3D printed a ... thing

Okay, so, as we're all hunkered down and dealing with this pandemic, some people are taking to a new hobby...

...well, I've already got a bit of a tinkering hobby.  Lots of folks have called me a 'gadget guy' over the years.  Prior to the whole shut down we had ordered a 3D printer for the office, and as the delivery date neared, I diverted it to come to my house as the building was closed to even mail.

So, now I have something new to tinker with.  I'm learning.  It's not as simple as a photocopier ... hit the button and you're good to go.  Nope.

But it's fun.

Now, I don't know why, but this little mechanism I printed off, I've had a tremendous amount of joy printing it.

It's this file from Thingiverse:  https://www.thingiverse.com/thing:3688892https://www.thingiverse.com/thing:3688892

I know it's not 'Android related', and maybe there is a way to print from my device to it (currently, because I don't have a Mac or PC anymore, I use Polar3D to connect to the printer and slice from there then send the gcode).

Let me know what hobbies or skills you're learning during this time.  Or, if you're 3D printing, what do you have?  What have you printed?  Any tips or tricks for a newb like me?
