It is easy to create my own files in multiple formats including print ready format which makes it relatively easier than other software I have used so far (Cura etc). The file size restriction can be quite irritating at times but that may improve over time as they develop their technology further or perhaps we will just need more powerful hardware/software combination! For now its still ok though there are ways around this by using different apps like Cc2d where you basically convert your model into another application before uploading them online thus increasing overall upload limit per week significantly without having an upfront cost - not sure if thats legal btw haha :) Just go through tutorials first then look out what options suit best depending upon how complex each part needs to get printed / rendered prior being uploaded onto any platform e.g zebra printers would require very good rendering power whereas inkjet printer could work well enough although resolution should.
