Dummy 13 1300% – Screw‑Fit Chest Frame

This is a reinforced Chest Frame upgrade for the Dummy 13 – 1300% model. The original remix by zwillia121 split the Frame_Chest into two parts, but at this scale the press‑fit connection is extremely difficult to make both tight and crack‑free. To solve this, the LOWER Chest Frame has been redesigned to use a bolt‑together connection.

Hardware required:

• 4× M5×60 mm bolts
• M5 nuts
• M5 flat washers
• Tightening requires two M10 sockets

Assembly is intentionally robust but tricky. You must first assemble the two large Chest Frame parts, then slide Armor_Chest_Lower onto the frame. Only after that can you place the assembly against the dummy — there is just enough space to slide in the small bracket and insert the bolts before tightening everything down.

This modification ensures a strong, reliable connection between the Chest Frame and Frame_Abdomen without stressing or cracking the plastic.

Fully compatible with the original Dummy 13 printed at 1300% scale.
