Synology NAS DS218+ Casing with filter v2

本模型用于群晖NAS DS218+，通过增加外壳、前过滤网和后密封框，为NAS进气通道增加空气过滤，减少灰尘进入NAS内部，进而降低出现故障概率。本案例中，外壳采用PETG材质打印，前过滤网采用ASA材质打印，后密封框采用具有弹性的TPU材质打印。最佳实践经验：1、由于ASA材料在打印后会收缩，前过滤网可以轻松放入外壳内，如果使用PLA或PETG材料，可能需要对前过滤网外圈与外壳装配位置做轻微修改，留少许间隙；如果前过滤网装配较松、易脱落，可以使用胶带调整间隙。2、后密封框需先放入外壳内，再把NAS插入后密封框开孔位置，最后将前过滤网放置在外壳装配位置。3、不需要额外的紧固件。 最后Enjoy it！This model is used for Synology NAS DS218+. By adding the casing, front filter and after-sealing frame, this system adds air filtration to the NAS air intake channel and reduces the dust entering into the NAS interior, which in turn reduces the probability of malfunctioning.In this case, the casing is printed in PETG, the front filter is printed in ASA, and the after sealing frame is printed in resilient TPU.Best practice experience: 1. As the ASA material will shrink after printing, the front filter can be easily put into the housing; if PLA or PETG material is used, it may be necessary to make slight modifications to the assembly position of the outer ring of the front filter and the c
