Hard to get last pieces of tissue paper? Never happen again
Tissue papers Always On Top now!

A plate and a set of spings is added to the tissue box, so tissue papers will come up close to the lid, instead of droping back to the box and hard to get.

I am by no means the first to have this idea, but I didn't see anyone who uploaded any 3D printed sping tissue box designs, so I do it.

Features:

• Fully 3D printed, no other components needed
• Only sping components need supports
• PETG@@0.2mm layer height 15% infill tested, available to use it
• About springs:
  • If you seek PERFECT PRACTICALITY, metal springs are perfect choices obviously. And you can just ignore all the hints listed below
  • I'm using PETG with 0.2mm Standard @BBL P1P, choosing a 3.5mm wire diameter spring model, it works perfectly
  • Each type of filament has different mechanical property, influenced even by the brand, which means I can not give you a formula to choose one, you need some tests
  • I don't recommend PLA filament, which is often fragile, PLA-silk even more
  • Spring model named by rule of WD_X(_Y), e.g. WD_2_5 for 2.5mm wire diameter spring model
  • I can not guarantee the elasticity of the spring can keep for long time, 1 month? 1 year? 10years? I just don't know, please be advise
  • You'll need a good tuned 3D printer with good part cooling, because of these spring overhang wall features
    
  • If your printer just don't work, try to reduce layer height to 0.08mm will solve the overhang wall problem, nearly delete all these features, and will definitely increase the time you need to print.
  • Because of the low stiffness of spring parts (that's why it's called SPRING), I highly recommend you to manually add tree-style supports each 120° or less degrees to prevent the shaking.
    
  • If no supports at all, I 100% guarantee you a spaghetti
    
  • Smaller WD means harder to print, less stiffness and need more supports
    
    

总是很难拿到最后几张纸巾？没事！

现在纸巾永远在最上面了

在纸巾盒里添加一组弹簧和一个底板，这样就能在纸巾只剩下几张的时候贴紧上层，而不是掉回纸巾盒里难以抽出。

我肯定不是第一个有这个思路的，但是还没有在这里看到其他人进行3D打印的弹簧设计，因此我设计了这个纸巾盒。

特性：

• 完全3D打印，不需要购买其他附件
• 只有弹簧需要添加支撑，其他零件不需要
• PETG@0.2mm层高 15%填充工艺测试，可以正常使用
• 关于弹簧
  • 如果你追求完美的实用性，那么显然购买金属弹簧是更好的选择，可以跳过下面的提示了
  • 我使用PETG材料，0.2mm Standard @BBL P1P 工艺，选择线径3.5mm的弹簧模型，表现完美
  • 每种打印材料的力学性能都不一样，甚至品牌都会有影响，因此无法给你一个通用的准则，你需要选择最适合你的那一个，需要一定的测试
  • 不建议使用PLA，因为PLA往往较脆，丝绸PLA更是如此
  • 弹簧的命名后缀 WD_X(_Y) 代表了线径，例如WD_2_5代表2.5mm线径的弹簧
  • 3D打印弹簧力的衰减我并没有测试，一个月？一年？十年？我不知道，并不能保证长期可用，请注意这一点！
  • 需要一个调教的不错的有足够冷却的打印机，因为弹簧有一些悬空墙特征
    
  • 如果不行，降低层高至0.08可以基本消除悬空墙，但是也会显著增加打印时间
  • 由于弹簧的低刚度(这也是为啥它叫做弹簧)，无论你使用什么工艺，都建议手动每隔120°或者更近的间隔添加树形支撑，避免晃动
    
  • 如果你一点支撑都不想加，我保证你100%会得到一团炒面
    
  • 更细的线径意味着更高的打印难度，更低的刚度和更多的支撑
