Wash Hands Sign (Inspired by ISO-1019)

thingiverse

After searching for inspiration from suitable signage which gives a clear message about washing one's hands, I came accross this one from Google images (ISO-1019) and with a few edits and tracing in CAD, based my result on that. In the ISO system, a white image on a blue background means the indication is mandatory and this one doesn't need translation either! However, I believe there is license for a little colour in its implimentation, while retaining the original intent of the symbol/ signage. When printing out, the hands can be made in skintone PLA, the soap suds in white and the disc background in blue and white. The disc gcode file does have a pause-point for changing the filament colour from blue to white - at about 2.4mm of the printing height. The disc is 150mm in diameter, just the right size to fit on a standard bathroom tile. The hands and soap suds have recesses in the disc, so it's merely a case of choosing flat or fillited (/rounded) as required and then playing around with how you want the colours done - flat skintone-coloured hands with fillited soap suds gives a little more emphasis to the soap, while if all are done in fillited form the effect is also quite pleasing. The choices can be rounded, flat or any combination inbetween... For fixing the final choice of flat or rounded elements, a thin smear of contact adhesive (if you want to change things later), or for more permanency. CA glue will do the trick. The 3D 'puzzle' method can also be used as a tactile teaching tool. Have fun!
