I am curious,
What model of 3D printer did you use to make this?
Is it a steep learning curve?
Well, I use a Creality CR-10. I've had it about 2 weeks. I also have an Elegoo Saturn S that use had for a year. The new one is FDM, other one is SLA.
FDM uses filament that is melted, the SLA uses resin harder by UV.
In my spare time I taught myself to use Fusion 360, so I design stuff and sell it online through a friend in Texas.
My full time job is a Field Service Technician setting up Ultra High Pressure water jet cutting systems. So, I have a bit of background in CNC machines.
For me, it is a fun hobby. If you like to tinker, are good with troubleshooting and can get around a computer, it is easy and fun.
You can get files pre done on the web if you don't want to learn to make your own
