Hello, I am extremely new to this and didnt even know this sort of community existed! I am determined to one day build my own Mando suit (Din Djarin) but I have absolutely no idea where to even begin. I would like to get a 3D printer and go that route but I dont know which one would be best for making Mando armour. If someone has any suggestions on 3D printers, software, templates, etc. I would greatly appreciate it! Thanks! 
Welcome the biggest thing I would do first is get in contact with your local clan, which from your profile is the Dallas area.
Murraan Clan. They will be able to help you find materials to build your kit locally and help with sizing and templates. Figured you should throw a introduction in your Clan's message board so you can meet some local Mercs to start off with.
Research, research, research and ask as many questions as you can. There are a lot of great WIPs here on the forums and some excellent resources in
Jadd Halls of Knowledge for tutorials, guides, and visual references.
You'll also want to read the
Comprehensive Forum Guide. This has a lot of info, please take the time to read through all of it.
Pictures are worth 1000 words, so figuring out how to post photos is key to making a good WIP (work in progress) a great WIP.
Posting pictures the linked guide is super helpful.
