This is a spudger tool I designed in Fusion 360. It's for those moments to help with Transformers when something needs to be pried open and your fingernails won't cut it. It has a 10mm and 5mm end so it's good for prying small things open, and a larger curved edge to help open larger things. There is also a 5mm peg to help leverage if Transformer fists are hard to open. And because this is plastic, there's less of a chance of damaging your toy (than if you used a screwdriver or something).

It's probably better to print this in PETG but this is PLA and it is holding up nicely.
