Filament marker for PTFE tubes

prusaprinters

<p>Yes, I know, one can see what color of Filament is loaded in which ptfe tube. But sometimes it is hard to differ between red and magenta, or I just dont remember if I loaded the black PETG or the black PLA on the masterspool I was too lazy to mark correctly then.</p><p>So first thing I do now when I load new filament is to print this little marker (approx. 6 mins.) with it, and clip it on the ptfe tube.</p><p>Blenderfile is included so you can mark your super exotic coconut infused pina colada filament too ^^.</p>
