Grew - Blaster MXL dùng magfed ít linh kiện phần cứng

This is the blaster I designed when I wished I had a Big Greg. It is Grew, the Greg we have at home.

It is a low hardware magfed bolt-action MXL stringer blaster
Goal was to be able to DIY it for under 70$ including hardware and filament.

THIS TOY CAN SEVERLY HARM OTHERS. IT IS UNSAFE TO SHOOT ON LIVING BEINGS AT UNRESTRICTED FPS.

ONLY USE IN GAME AFTER AN ADEQUATE CHRONO TEST PROVE YOU ARE UNDER SAFETY LIMITS.

Can be tuned from HvZ levels up to 200fps, depending of the version you choose to print :
   - 1 loop of 4mm                      TBD        (HvZ version - using short barrel)
   - 3/16" or 5mm                      TBD         (HvZ version)
   - 2 loops of 4mm                   TBD         (HvZ version - using short barrel)
   - 2 loops of 4mm                   TBD         (HvZ version)
   - 1/4" or 6mm = K25              TBD        (HvZ version)
   - 3 loops of 4mm = K25        TBD        (HvZ version)
   - 3/8" or 9,5mm = K14           TBD        (HvZ version)
   - 4 loops of 4mm = K14         TBD         (HvZ version)

   - 1/4" or 6mm = K25              TBD        (Long Draw version)
   - 3/8" or 9,5mm = K14          170fps      (Long Draw version)

   - 1/2" or 13mm = K12 + K31  200+fps (Long Draw double-bolt version)

It is compatible with Evan's Full Length MXL mags.

ATTENTION : Please read the instructions in the .txt files as it needs specific slicer settings to ensure no zipping sound when priming and a good dart flow.

Using the 3mf files is strongly recommended.
