Saved my ass when the kid remembered she needs a pencil case the day before the first day of school :-) Great model, thanks!
Materials used (what I had on hand at that moment):
Graphite tip – Prusament PLA Galaxy Black
Wood – Gembird PLA White
Body – Prusament PLA Azure Blue
Collar – Prusa PLA Pearl Blue
Rubber – Verbatim PLA Red
I only had some trouble gluing the "body" to the "wood" part – maybe that's because of the coarse resolution I used, but it wasn't much better even after sanding the contact surfaces smooth.
