Yeethammer - Reinforced Breech Lifter

I got a little too excited while using my Yeethammer and kept breaking the Breech Lifter pins.  

As a result, I modified the breech lifters to be reinforced by an M3 screw or bolt so you can Yeet to your heart's content without fear of snapping them. 

Requires: 

2x M3 x 10mm Countersunk screws

OR 

2x M3 x 8mm bolts

Printer settings:

• 4 Walls
• 4 Top wall
• 4 Bottom wall
• 15% Gyroid infill
• No supports needed
