There are two predominantly ways of converting a #SVG to #STL.

1. Online via simple converters. There are two cons with this method: first your project becomes public for a specific time period with the P0 license and if an option for a base extraction exists, it is difficult to align it to one specifications.
2. Via desktop apps like #blender. This gives better fine tuning for the cost of time it takes to convert the files. It is a minimal time difference.
