A good printer for small alphabet charms?

[Hcull]

My wife has just found out that alphabet charms she uses in bracelets she makes have been discontinued. As these charms are important for her business I am thinking the best replacement for them would be to buy a 3d printer and make them ourselves albeit in plastic instead of a metal alloy. From what I have found so far today on the internet I can use a silver metallic filament, so my hope is that they will look okay.I have been tempted in the past to get a basic 3d printer to play around with so all in all it makes sense to get one. However as it wont be used purely as part of a hobby I dont want to use it for a month or two and then come to the realisation I should have bought a better/more suitable printer.I have attached a jpeg with the charms as an example of what I will be needing to print and on the image there is the sizes of the charms.I am grateful for any advice.
