I couldn't find a blade holder that fit as a single print on Bambu P1P.  This is designed to print within a 250x250x250mm print area WITHOUT any supports.  Will hold 5 blades and is designed to stack vertically on the wall.  Add another set and there will be an additional blade slot.  I printed with eSun PLA+ using a 0.6 nozzle but 0.4 should work fine, just make sure you have thick walls and infill.  Adaptive Cubic worked well and fast.
