===English version description===

[Description]

1. I have been waiting for a long time. I have been playing V3.0 version for the past few days. I have strengthened its crossbow arm and adjusted its bowstring. In actual testing, it can easily shoot arrows into cardboard by about 7cm. However, I still feel that it is not excellent enough. The main problems are the following: the greater the tension, the easier it is for the nose to tilt up, which greatly affects launch; Secondly, the tail of the base is too short, making it a bit difficult to hold in hand. So based on the V3.0 version, after several days of testing and modification, I now solemnly recommend my fourth version of the Zhuge crossbow (simple composite version) to everyone. It solves the problem of the nose lifting, and now the nose no longer needs to be tied with rubber bands. It adopts a simple composite bow structure, while strengthening the base and length, making it more comfortable to hold in hand. The tail can be pressed against the chest like a stock, making firing more stable.

[Features]

1. Super large size, longer shooting distance.

2. Specially designed for adults, toys for old boys.

3. Support the continuous firing of ten bows and arrows.

[Print]

1. It is recommended to use PETG or PLA consumable silk for printing.

2. Please enable the suspended support for printing.

3. Different printers, consumables, and printing quality vary. Therefore, before printing, please adjust the printer and consumables to avoid printing failure and material waste.

4. For safety reasons, it is recommended to use normal printing speed. Of course, you can try turning on sport mode printing (I used PETG consumables to print myself, and after printing 5%, I turned on sport mode and the printing quality was completely fine).

5. After printing, please use tools such as blades, tweezers, etc. to carefully remove the support material, especially the support material of the magazine model. You need some patience and be careful not to damage the model.

[Safety Warning Statement]

1. Do not give this toy to minors to play with.

2. Please keep the toys out of reach of children.

3. At any time, do not shoot at people or animals, be sure to pay attention to safety.

4. Please comply with the laws and regulations of your region.

[Prepare parts]

1. Four M3 * 30 screws and four M3 nuts.

2. Four M4 * 45 screws and four M4 nuts.

3. High elastic solid slingshot rubber band (used to act as a bowstring).

4. 3D model strong adhesive (used to bond the main body of the crossbow).

5. Coarse sandpaper and fine sandpaper (used for polishing bullets).

[ Frequently Asked Questions]

1. Is the assembly hole too tight to be inserted?

Answer: The position of the hole can be slightly enlarged, and the shape of the assembled part can be appropriately polished.

2. Is the assembly hole too loose and is the insertion loose?

Answer: 3D models can be used with strong adhesive to assist in assembly.

3. Can bullets not be fired smoothly?

Answer: Due to the horizontal printing of bullets, in order to prevent them from easily falling out of the machine head, the gap between the launch pipeline and the bullets is relatively small. The solution is as follows: Use sandpaper to polish the bullet, test it while polishing, until the bullet can be fired smoothly (note: do not polish too much, otherwise the bullet can easily slide out of the machine head).

4. Is the range of the crossbow too close?

Answer: Please replace the bowstring material and tighten and shorten the length of the bowstring appropriately. In theory, the greater the force required to pull the bowstring, the farther the range.

5. May I play with this toy with the children?

Answer: It is absolutely not allowed. Please do not give toys to minors to play with, in order to avoid personal injury accidents. Minors lack good control and are not clear about laws and regulations.

【描述】

1.久等了，这几天我一直在玩V3.0版本，我对它的弓弩臂做了加强，以及调整了弓弦，实际测试能够轻松将箭头射进纸板7CM左右，但是我还是觉得它不够优秀，主要存在以下几个问题：拉力越大，机头越容易翘起，非常影响发射；其次底座尾部太短，拿在手里有些费力气。于是基于V3.0版本我经过几天的测试修改，现在隆重给大家推荐我的诸葛连弩第4个版本（简易复合版），它解决了机头翘起的问题，现在机头无需再用橡皮筋捆绑，并且采用了简易的复合弓结构，同时加强了底座和长度，拿在手里更舒适，尾部类似枪托一样可以抵在胸口，让发射更稳定。

【特点】

1.超大尺寸，射击距离更远。

2.专为成年人设计，老男孩的玩具。

3.支持连续发射十支弓箭。

【打印】

1. 建议使用PETG或PLA耗材丝打印。

2. 请开启悬空支撑进行打印。

3. 不同打印机、不同耗材、打印质量不一样，因此打印前请调试好打印机和耗材挤出流量等，避免打印失败，浪费材料。

4. 保险起见，建议使用正常速度打印，当然您可以尝试开启运动模式打印（我自己是用PETG耗材打印的，打印5%以后，我开启了运动模式，打印质量完全没有问题）。

5. 打印完成后，请用刀片、镊子、等工具小心移除支撑材料，特别是弹匣模型的支撑材料，您需要一些耐心，注意不要损坏模型。

【安全警告申明】

1.请勿将此玩具交给未成年人玩。

2.请把玩具放在孩子够不着的地方。

3.任何时候，不要向人或动物开枪，一定要注意安全。

4.请遵守您所在地区的法律法规。

【准备零件】

1. 4颗M3*30螺钉、4颗M3螺母。

2. 4颗M4*45螺钉、4颗M4螺母。

3. 高弹力实心弹弓橡皮筋（用于充当弓弦）。

4. 3D模型强力胶水（用于粘合弓弩主体）。

5. 粗砂纸、细砂纸（用于打磨子弹）。

【常见问题】

1.装配孔是否太紧而无法插入？

答：孔的位置可以进行轻微的扩孔，也可以对组装件的外形进行适当的抛光。

2.装配孔是否过松，插入是否松动？

答：可以用3D模型强力胶水辅助组装。

3.子弹不能顺利发射吗？

答：由于子弹是水平印刷的，为了防止它们轻易从机头掉出来，发射管道和子弹之间的间隙相对较小。解决方法如下：用砂纸打磨子弹，边打磨边测试，直到子弹能够顺利发射（注意：不要打磨太多，否则子弹很容易滑出机头）。

4.弓弩的射程太近了吗？

答：请更换弓弦材料，并适当收紧和缩短弓弦的长度，理论上拉弦需要的力越大，射程越远。

5.我可以和孩子们一起玩这个玩具吗？

答：坚决不可以，请不要将玩具交给未成年人玩，以免发生人身伤害事故。未成年人没有良好的控制力，对法律法规也不清楚。
