Dummy 13 - TPU ball joints for version 1.0

Remixed inner frame of the 1.0 model to use TPU ball joints. This results in a stiffer model that's less prone to sagging or loosening over time. The frame parts are printed with pegs that the TPU balls press onto. It is compatible with Dummy 13 V1.0 parts and armor.

I used Bambu PETG HF for the frame and Siraya Tech 85A TPU for the balls.

Re-implemented from scratch for the 1.0 models based on luu0898's model.

Plate 1 - PETG Frame

• Layer Height: 0.10mm recommended
• Orientation: follow print instructions for the original Dummy 13.
• Supports: manually paint supports onto the floating pegs. Auto-supports will work, but it'll add supports in unnecessary regions.

Plate 2 - TPU Balls

• Layer Height: 0.10mm recommended
• Orientation: the balls have a flat section that should be on the print bed.
• Supports: none

Plate 3 - PETG Frame, feminine chest

• Same instructions as Plate 1 if you're using the official Dummy 13 - feminine torso parts.

Replaced the inner frame ball joints with separately-printed TPU parts.
