Material Notes

PLA is fully sufficient for normal play and performs surprisingly well with this design.

If you want to level it up:

• Use PETG for better durability
• Use ABS / ASA for higher heat resistance
• Use PLA+ or Tough PLA for added strength without losing ease of printing

Stronger filaments will make the bat more impact-resistant, especially for harder swings.

HOW TO INSTALL THE KNOB OF THE BAT→ 

Try to strangle the end of the bat with your hands and push the knob onto the bat. Like this: Depending on your own printer tolerances, it may be too tight or too loose. If it's either, then sanding/ a dab of hot glue is key.
