Circle helper target stencil

Beschreibung

After I published my last project I got a request to make a circle helper for making targets on A4 pages. That's why I have on one side holes for 1" 3" 5" 7" diameter circles. But then I thought why not to expand it to make a bit more use of it. There is a center line so you can make circle graphs. The other side has holes after every cm. There are small circles on the rim every 5 degrees. The holes are 4mm diameter so you can use markers, but normal pens and pencils are fine too. You can use it on a white board, might be good in the classroom also. You can make graphs or teach kids about electron shells or something like that. NOTE: use some kind of oil in-between the two parts (I used vegetable oil from the kitchen), you can take it apart oil it and put the two parts together. I printed with PLA.
