♨️ ANNEALING — Hardening Your Chess Pieces

Annealing your PLA models can improve strength by 10 – 20 %.
If you plan to play with these sets regularly, annealing is highly recommended.

If your goal is display or occasional play, annealing is optional.
The appearance and finish remain unchanged.

Please note: 

Because I’m retired and on a fixed income, I print these models at a smaller scale to save on filament. All of these models are printed at 70% - 80% of the model uploaded size. 

♟️

Thank you!  Thank you!  To all of you who Boost my uploads.  Because of YOU I can get my filament now from “Maker's Supply”, saving me from using real money. 

♟️

These creations are made purely for the joy of sculpting and sharing. Printing at a reduced scale can sometimes affect the quality of fine details; printing at full or larger sizes will yield smoother, more refined results.

♟️

Also, as a 77-year-old maker with hands that sometimes have a mind of their own, I occasionally have to use a little hot-glue surgery to reattach delicate parts. Please handle models with care—especially thin necks, joints, and fragile connectors. Take a moment to study your model before removing supports… or you might find yourself reaching for the glue gun too! 🥲
