About this 3D model

A1mini enclosure can be printed on A1 itself, the enclosure size is a circle with a diameter of 180, which is just the printing size. It is important to note that there should be tight-fitting supports inside, hand-drawn supports may exceed the printing size and can only be modified slightly. Or you can scale the printing proportion (I haven't tried it myself). The lid of the enclosure can be bought directly from Taobao, choose a 3mm thick circular acrylic plate with a diameter of 176, it costs only 5 yuan per piece. Due to size constraints, ordinary material trays are difficult to fit, here I provide a Bing material tray, but I haven't drawn the axis, if you don't buy their materials, you will have to rewire it yourself. The enclosure has two openings, one for filament and the other is for hot air to be sent in later, which will save the trouble of replacing the dryer. The filament outlet can be equipped with an air tube connector, but it can be used without it, and it may even block the filament if it is equipped with one. The hygrometer is an embedded hygrometer bought from Taobao, costing 5 yuan each, it's not very accurate but has a good price-performance ratio.
