Very easy print ~5 min. Works well with the standard settings. Printed in Bambu Lab PLA Basic.

I just wanted something lightweight that will fit most pens. Any pen of 9.5mm to 10mm should fit. The tab is for glueing into a journal / notebook. I used some all purpose glue, but super glue might work better. The print takes less than a gram and I wanted something permanent that would not fall out or get lost, like e.g. a clip on version.
