Hot bed scraper - Quickly replace the shovel head

I have designed a large inclined shovel that can quickly replace the shovel head, with a total length of about 120mm and a thickness of 6mm. The shovel handle can be reused, and the shovel head can be freely replaced to achieve the freedom of the shovel blade. One shovel is enough. Specifically, it has the following characteristics: 1) It can quickly replace various shovel heads, providing three types of shovel heads with widths of 30mm, 50mm, and 66mm, and can also be designed and replaced by oneself; 2) Can be quickly replaced, firmly connected, and designed with high and low surfaces, the shovel handle will not interfere with the shovel object; 3) The shovel handle is reusable and can significantly reduce consumables, with a length of 90mm and an elastic design for a good grip. 4) It can be printed quickly, with one set (one shovel handle+one shovel head) printing taking only about 30 minutes and consumables of about 13g.
