Gap Spacer Sunlu S2

🛠️ Smart Tweak for Filament Dryers Some filament dryers do a solid job keeping materials dry, but limited airflow can hold them back. Instead of drilling holes or modifying the device, I went for a simple and elegant fix — a custom gap spacer that slightly lifts the top lid.🌬️ This small adjustment improves ventilation, and surprisingly, it brings the humidity down to below 20% during heating! The spacer fits snugly onto the bottom half, and the lid slides in with ease.No tools, no hassle — just better drying performance. 🔧🔥
