jar is from small yoghurt, file is for mesurement purposes, but you can print it also

there are few support structures which need to be removed after printing

1) in the main body, where knob meets coin holder

2) in the coin holder to allow coin be dropped

coin holder need to be pressed little bit to actuate knob

main body shoul be printable without supports, but the top of cylinders would be rough and need to be sanded

bgcode files are from v1 and are little bit different from this version
