Optimization Notes for the New Body - Torso and Joints

New 58cm body

Since the mass-release of the previous 57-body in 2019, we addressed some minor known issues in 2021 and further updated it to Version 3.1 in 2023, primarily optimizing the stability of thigh and arm joint movements. It’s fair to say that the 3.1 version of the 57-body has become a relatively stable and mature product. However, with accumulated experience and technical advancements, we felt it necessary to overhaul certain previously overlooked aspects of the design and create an entirely new body.

Beyond the hand and foot modifications mentioned in the previous post, here’s a brief overview of the more noticeable changes:

The bust, waist, and hip measurements of the new 58-body will align more closely with our clothing mannequins, with errors kept within 1mm.

The interlocking slots between chest components have been redesigned for better fit and smoother transitions, reducing the likelihood of slippage.

The thigh joints have been completely reworked. The original locking mechanism has been removed, and with a more rational design, the legs can now stay in place without a lock, even allowing for knee-hugging poses. Additionally, unlike the common habit of pulling the joint ball apart for adjustment, we recommend operating the thigh joint with one hand whenever possible.

Knee movement is now smoother and also supports one-handed operation.

Other detailed improvements are hard to fully describe in words, so we hope owners of the new body can actively share their discoveries. We sincerely hope our new body brings even more joy to your doll-playing experience. Thank you for your support over the years, which has allowed us to continue doing what we love.
