This is a set of road sign posts in 7mm/ft or 1/43 scale that I designed for use on my model railway. I prefer to the use the versions with just the mounting brackets and then I add the roadsign printed on thin card. I have made several different arrangements of brackets to suit various kinds of signs commonly found in the UK.
I have also included versions of the file with the basic shape of the sign (circle/triangle/octagon) included for if you prefer to print the signs on paper to glue on.
There is also a bare post with no brackets that might be useful if the others don't suit your needs.
I sliced the files in Lychee and printed them on an Anycubic Photon Mono X, using Siraya Tech fast white resin.
