材料
三件式冲压夹具
- 4毫米 中密度纤维板（MDF）
- 1毫米 钢丝绳
- 6-20毫米 木螺钉
- 透明胶带
护罩
- 0.5 毫米厚的PET聚酯塑片 或者至少是 醋酸纤维塑片 (Acetate sheet)

制作步骤
三件式冲压夹具
1
下载适用于您的激光切割机底座的三件式压模夹具的激光切割模板。（切割模板的尺寸显示在文件名中。）根据模板文件对MDF进行激光切割。
2
从激光切割机上卸下冲压夹具的3个部分。将钢丝绳切成模板A和C部分中虚线的长度。将金属线用胶带贴压力夹具A和C凹槽中的虚线上，确保不要偏离虚线，也不要超出虚线的两端。
3
用短木螺钉将B部分装到顶部A上。将组合起来的A和B部分连接到一个基板上，以保证压力均匀分配在夹具表面上。对C部分执行相同的操作。
护罩
1
下载适合您激光切割机床身的HappyShield激光切割模板。 （切割模板的尺寸显示在文件名中。）
2
按照模板文件激光切割透明塑片。注意调整激光切割机的功率和速度设定，确保其能够切穿整个塑片材料。
切割后，从激光切割机上卸下得到的防护罩和防滑夹。如果需要，用酒精擦拭护罩和夹子的边缘，或用任何肥皂清洗，以除去塑片上的激光切割残留物。
3
将塑片插入三件式冲压夹具中，按压形成弯曲的褶痕。 Insert shield into the 3-part press jig and press to create the curved creases.
4
切下400毫米长的松紧带。将穿过两端的摩擦夹。将松紧带两边与两个防滑固定夹连接。
5
将连接好的防滑夹从护罩带孔向前穿出。
