This warning sign is intended to be placed in your mobile phone holder on your motorbike, when it is parked with a brake lock installed.
The idea is that you will probably not leave your mobile phone on your parked motorbike, so the phone holder is empty anyway. And it is place right in front of you when you sit on your bike, so you will very likely see this sign if you are about to start the bike and drive away.
Printing sign sign is very simple, you can use basically and printer and any material you like. Not supports or brim are needed and the infill is not critical (I used 15%).
Of course you can add a color change in Pursaslicer and have the top 1 mm printed in another color. I simply used a black pen and quickly colored the surface of the letters in black. We will see how quickly that wears off. I can always do another one with color change.
The part in the picture is made from PETG orange from DasFilament.de.
The author marked this model as their own original creation.
