About this 3D model

Some modifications have been made based on actual usage experience, in addition to the original version. The pipe head has been chamfered to prevent damage from hitting the front crossbar when the pipe length is cut incorrectly. Of course, this usually happens to beginners. When I heard about this situation, I modified the model. The slanted support sometimes interferes with the drag chain. In actual use, it was found that it did not play its original role. After the drag chain was skewed once, I decided to remove this support. The diameter of the buckle that connects to the tool head has been thickened. Now PLA and PETG are easy to insert, but they are very brittle. The original buckle sometimes breaks. The purpose of this guide is to prevent the filament tube from scratching the glass on the lid. It can be fixed by the filament tube itself. As long as it can be roughly connected to the buckle of the tool head, there is no need to completely lock it. After thickening, installation and disassembly are very convenient, and it is much easier to install when plugging the tube.
