I remember in 1996, going to a tiny computer shop and picking up a 14k modem for about 30 pounds. He handed me an AOL cd rom and within 20 minutes I was on the web. I will always remember those of beeps and squeaks as the modem connected.

I do this right regularly. I created a huge trash can shape container using 8 separate pieces printed in PLA. I then glued together with CA glue and welded the pieces with a 3D pen to make the joints stronger.

A couple of things to remember:

3D pen don’t push the filament like a 3D printer does. You have to slow the flow of the pen down, and let the filament bind to the layers below

There’s a big difference how different PLA will behave with a 3D pen. Some filaments won’t stick as well like others

You have to mimic the behaviour of a printer with the pen. So you have to lay down layers of filament, rather than trying to make it behave like a glue gun.
