Dryfire training buffer cartridge 9mm

I made this version of dryfire buffer cartridge to test the H2D capability of printing with TPU. I used TPU 95 HF on the right extruder (loaded manually) and TPU AMS on the left extruder over the AMS 2. It worked very well. For your information: TPU 95 HF got stuck in the AMS 2, although the instructions say that only AMS softer than 95A should not be charged. TPU 95A works fine for dryfire training, I use this for years. But TPU AMS only works for the logo, it is to hard for the bottom and would get damaged from the extractor. There is a second printprofile for none H2D printers (one colour).
