My own cad drawing skills are still at basic geometry stages so a learning curve ahead for me. I do find the process fascinating tho as i grew up with traditional modelmaking both in hobby and later in professional fields, especially in recent years with the emergence of accessibly priced high quality resin type printers
Iv found 'secret projects' type drawing files avaliable online for 3d printing a bit hit or miss so far (the latter no doubt due to lack of information obtained by the artist) if anyone comes across any of possible interes or indeed has drawn up similar please feel free to share
Best wishes, Joe
