Based on the V3 update of the shovel, the V4 version has been iterated. The V3 version is mainly used for medium to low intensity use (after all, the shovel head is only 2g), while the V4 version is used for high-intensity use, which can be used to remove large printed parts (which can be removed by prying), and can also be used in conjunction with the V3 version. The V4 version has the following characteristics:

1. Satisfy the need to remove objects of different sizes while protecting the hot bed;
2. Reasonable connection structure design, stable connection and easy disassembly；
3. Strengthening, enlarging, and thickening the structural design, combined with local strengthening of printing configuration, greatly enhances the connection strength between the shovel handle and shovel head;
4. Increase the size for easy exertion, with dimensions of 154mmx45mmx9mm;
5. Multiple placement methods: magnetic suction (magnet diameter of 8mm and thickness of 2mm), door handle placement (supporting X1, p1s, 2s), or hanging on a hook for placement；
6. Setting the claw part on the shovel head further increases the durability of the shovel handle.
7. Multiple blade angles: 32° (default blade), 25°, and 16.5° blades meet the requirements for multi-angle cutting.

The V4 version is not a simple enlargement of the V3 version, but a brand new upgrade. It is recommended to use it together with the V3 version to meet the needs of 3D printing for shovels and protect the hot bed.

Installation Instructions：

After removing the support of the shovel handle fitting hole, insert the fitting column of the shovel head parallel into the shovel handle fitting hole, and at the same time, the claws on both sides of the shovel head are in place with the shovel handle.

Disassembly instructions：
