COVID test toy

thingiverse

A Toy COVID RAT (rapid antigen test). obviously not an actual test, you can slide the slider on the side to select blank, negative result or positive result! Assembly: Print the 3 plastic parts. print to paper part cut out one of each part from the paper and very carefully cut the 2 slots in the slotted part glue the paper with the red lines to the top of the slider, the oval on the paper goes on the same end as the oval on the plastic the paper has 4 copies of the top piece, you only need 1 but now you can have 4 tries to cut it right. glue the part with the red stripes to the slider part, with the oval marking on the matching end. glue the paper part with the slots to the bottom of the top plastic part, put the printed side down so you won't see it when its assembled. oval to the end with where you would put the 3 drops in the tester. put the lid on carefully, the clips are very easy to break, you may want to supper glue them when it all works slide the slider, you should be able to get all 3 states to show up, if not then the slots are probably cut wrong, the template was wrong but I fixed it before I uploaded it so it should be good now, alternately if something is back to front down it may not work properly. test all your dolls for covid! I originally made it to be fully printed, in red and white but white PLA is much more transparent than paper and the red showed through, it was OK, but using paper make is look more authentic, the slots are less visible, and the red doesn't show through I used a glue stick to glue the paper to the PLA I printed with 0.2mm layer height
