Parts for Welding Helmets

Hi

Very new to the 3d printing world but Im also a foreman in a welding shop. I have fifteen welders in my shop and almost all of them have different welding helmets and head gear. My problem is trying to find replacement parts for lesser known gear. The bits and pieces get damaged frequently and I was wondering if anyone made models of these parts considering the enormous community of designers. I cant seem to find anything here. If someone does design these parts could you point me in the right direction? Also I know Im not the only one with this problem so it might be a moneymaker for some enterprising designer

Thanks
