this is the tin set: (thicker set here: https://www.thingiverse.com/thing:3152883)
Printed in 2 colors (just stop at the layer where the symbols start and change filament if you have a 1 extruder printer like me).
and bought some magnets that where glued to the back...
And presto handy networking magnets for making diagrams on a whiteboard.
Only need for a marker is for the lines.
I've included the fusion360 source so you may change the text (now accomodates for 3 core routers (cr1,2&3) but you can change it ofcouse.
