I recommend PLA TOUGH+ or ASA 

PLA or PETG will work but most likely will crack over time.

✅ FEATURES :

🌀 Shock-Absorbing Flexible Neck - The flexible neck absorbs force so the swatter doesn’t crack under pressure.

🧩 Snap-Together Modular Handle - Built to snap together and stay locked - If your swatter head ever breaks, just swap it.
The handle is reusable. No waste. No tools. Just pull it out and replace.

🎨 Tested about 15 different designs and these 2 made the cut.
