plus plus (minus minus)

I remember this toy from like 2016 or earlier they were made out of rubber and now they are expensive to point of not worth buying this is why i just made this. On single print there is 30 of them they are basic for now but im open for any requests of other plus plus parts as they made more shapes now. This toy is pretty old and pretty fun they are small (20mm lenght, 4mm height, 12mm width) so can be transported practically anywhere which makes it fun to use for example at school.Printing them in multiple colors allows to make more beautiful creations. (or like the original has on box: animals and cars)recommended material: TPU as of original being made out of rubber to have grip on each other but i printed in PLA and works wellYou can sell them if you want i dont care i just dont know how to set the license to allow that.
