Settings for printing small text

[shaidas 0]

Hi All, I am just starting of in 3d printing. I have a monoprice select mini and barring the small bed size I am really stoked with it for the price. I designed a stamp in Tinkercad, did a make solid in Mesh mixer. I have changed the machine setting for a nozzle to 0.3 to accomodate the font. The model is oval at a height of 17mm. the font is about 3mm raised. I started by using a layer height of 0.088 , single wall, nozzle 195, bed 55, print thin wall enabled, speed 20mm/s with the model lying face up. This was the base setting..I have tried to play with a myriad of settings based on what I am reading but on slicing the font face always gets messed up. Even when I increase the model size to 200 % the results are not spot on. Can someone tell me what exactly if anything can be done or is it just that the walls being so thing, a high resolution print is not achievable. Would appreciate some reasoning behind any suggestions please. Thanks in advance for reading. The font is Lucida Calligraphy bolded. Here is the stl
