OP Wads for Black Powder Era cartridges
thingiverse
The STLs and OpenSCAD files will allow you to print over powder wads for 40 and 45 caliber straight walled cartridges. They have proved safe in my loads. If you elect to use them please be guided by experience and an abundance of caution. Use at your own risk Instructions Printed with ABS on an Afinia H479 using .15mm layer and solid fill. I've not needed any thicker than the 4mm wads so have no experience with thicker wads.
