This is a holder for the countless warning/caution signs from this platform.
I have printed and tested this with three signs from the model 181326-warning-signs. Each scaled up to 90.27mm x 79.32mm x 2mm to fit the format of a previously printed sign.
In general, hight and width don't matter. Only the thickness can't exceed 2mm. I did not test for a max/min sign hight. The unscaled sign holder has a length of 50mm and should be able to hold a lot.
I have uploaded a .step and .shapr file so you can easily edit it and print a custom version for yourself.
Glue stick and/or rafts/brim required! The part is really small and might not stick to the plate.
