portable laptop stand modified

通过对原模型打印后的使用，发现了一些痛点，对模型做了以下改进：1.横撑改成套子的形式，方便收纳；2.加入了磁吸，使得收纳时候不容易掉出；3.增加卡扣设计，使用时可以整体移动不散架；4.底部增加凹槽，可以自行粘贴硅胶条，使用时和桌面摩擦力更大，不容易挪动（当然，不添加也可以使用）。 需要6*3磁铁4颗。 Through the use of the original model after printing, some pain points were found, and the following improvements were made to the model:1. The cross brace is changed into the form of a set for easy storage;2. Added magnetic suction to make it not easy to fall out when storing;3. Add buckle design, which can move as a whole without falling apart when in use;4. Add a groove at the bottom, you can paste the silicone strip by yourself, and the friction between the desktop and the table is greater when you use it, and it is not easy to move (of course, you can also use it without adding).4 magnets are required for 6*3.
