Compliant Half-Size Blaster for 0.6mm nozzle.

This adds some small modifications to the BYU "One piece compliant Blaster” so that the trigger mechanism is  more positive locking and less likely to accidentally trigger.

I needed this modification when printing with a bigger 0.6mm nozzle that rounds the corners of sharp edges more.

To apply, download the original “Nerf - Halfsize.stl”  from 540528 printable and then run the OpenSCAD program provided here which loads this file and adds the mentioned modifications.

This improves the trigger locking mechanism to be more positively locking, in particular useful for “corner-cutting” fast prints that use 0.6mm nozzle. 

• Use slope to keep lock positively engaged
• More overlap of the 'catch' when pulling back.
• Round the corners of the lock-edges for realistic manufactured outcome (DFM).
