44/21 創客空間舉辦實作工坊，帶領學員使用 xTool F1 雷雕機打造專屬「載具鑰匙圈」！活動中除了教學載具原理與轉檔技巧，更讓學員實測比較木材與皮革的雷雕質感。現場還有學員發揮創意，用 iPad 手繪插圖直接雷雕，讓實用配件瞬間可愛滿分，為體驗活動增添滿滿亮點！

On April 21, Maker Space participants used the xTool F1 laser engraver to create personalized e-invoice keychains! They learned barcode mechanics, file conversion, and compared engraving effects on wood and leather. Some even engraved their own iPad illustrations on the spot, turning practical keychains into incredibly cute and creative accessories!
