I'm sure many have this problem of, what do I buy for the person who has everything I can already afford? 'cause I have that problem now. My dad has gone deep into 3DPrinting in his retirement (he handed me down my Ender 3). He's got both an Ender 3 and a resin printer, tho I can't remember what model.
I was hoping to pick the hive mind for some useful 3D printing related ideas that won't break the bank. Some useful utilities that maybe I hadn't thought of. I'd really appreciate any help.
Filament or spare parts is imo always an option (at least thatā€™s what I tell people who want to get me something). Otherwise ask if he has any plans regarding upgrades etc. and get him an upgrade kit?
A wash & cure station for his resin prints would be a good idea of he doesn't already have one. Mine really stepped my game up & I consider it an incredibly useful utility.
For his Ender I think some utilities like the Mintion Beagle camera or a filament dryer are very useful but also aren't everyone's first thought for an upgrade. Good luck!
