Update 01/2022 to present date - I'm not currently taking on any new commission jobs.
Radio Controlled Cars (mostly Tamiya) is one of my hobbies. As I build my RC projects I'll occasionally have a model that needs a part that doesn't exist, or one that isn't made anymore, so I'll try to design it to be 3D printed via here. If it works out the way I hope (or better than that!) I'll make it available on here for everyone else to buy because, simply, if I can use it then I'm pretty sure I'm not the only one who can.
Oh, occasionally I'll draw up stuff at someone else's request too...
