i´m very intrested in doing an own mando armor, and with the trashcan model, some pieces will be pretty easy.
but the helmet... is it some way to do it yourself, or is the only way buying it? it´s probobly already lots of threads about this, but i don´t know where to start
Or you can try making one in metal like I did, if you have access to a welder. You can get the measurements on tk409.com and build from there. Take a look at mine by finding "Metal Bucket" in the helmet section.
