Safety day counter sign with tags (Robot attack inspired) includes Meteors and Lasers

prusaprinters

I browsed prusaprinters for some wall art to embellish the empty stair case wall below my flat. The robot attack sounds just right for a last thought when leaving the house.To make it a little more difficult to remove, I designed an additional wall mount for earthquake-resistant fit.DesignChanges to the original designnumber tags will not hang, but slide in; allows three numbersthree options for wall mountingthree classic disasters to choose fromrobot attackmeteor strikelaser attacknumbers 0-9 complemented with infinity tag, and minus tag to allow for forecastsuseful when modifying the attached STEP files to cover for your personal disaster/safety awareness: the font used is from the transport family, available from https://www.roads.org.uk/fonts and used under Open Government Licence v1.0AssemblyThe number tags are intentionally a smidge too high. After a couple of swaps, they are easy to push in and out, yet still earthquake-resistant.Mounting Optionscomes with three choices for wall mountingby cordthis requires two screws 3mm x 5mm (0.12" x 0.2") and a cord that is knotted into a loopby magnetfour recesses allow for up to four magnets ø10mm x 5mm which can be fixed with a drop of glueby wallmount bracketa separate part to print, requires an M3 countersunk screw (>12mm), and an M3 square nut to lock the sign; and of course two screws to attach to a wall. The holes allow screws up to 3.5mm (0.14"). Centre line markings may support positioning.wallmount assemblyit's a good idea to level the block before tightening the wall screws (don't forget to put a mark on your finger too).  Fixation happens with a screw driver to the mounted block: I chose an inhex screw, the blade of the driver should be relatively long: a standard 2mm allen key won't reach the screw, but an electronics type or a long allen key with ball head will do. Turn the screw anti-clockwise to lock.PrintingI chose ABS, but every other filament should work fine. ABS will warp by a couple of millimetres, but didn't cause trouble in practice.Find the attached sample .3mf files to see the colour change height. Printed fine without supports.My print is 230 x 180 x 6mm. You may scale that down, but please consider screw/magnet holes getting smaller, and the typography may need a smaller nozzle than 0.40mm to still work.
