Good question! I found a papakura file of it, but it's confusing to me being someone who's never used that kind of construction before. I think I'll end up eyeballing it after making a simple pulce replica ( I met someone who says they'll 3D print a pulce for me) as a stand-in, using 3mm sintra and rubber/nylon strap. It's necessary for 501st approval (the holster not the sidearm).
