养了一只比熊犬叫糖糖，2025年7月9号生日，不巧昨天因为开空调吹到感冒咳嗽。首医给的药有一种叫“果根素”的肝胆口服液，每次需要喂食2ml，一时找不到合适的容器，就自己画了个小杯子。

圆柱形的缺点是微量的液体会残留在平底上，导致倒不干净，测量误差比圆锥台大。

所以我增加了0.2ml。 

用过后感觉很不错，上传给需要的人。 

总计两个版本： 

1. 直接打印。 

2.内置一个8mm*2mm磁铁的版本。

打印建议： 

100%填充  

使用建议： 

一只手轻轻敲开狗的嘴根部，另一只手用量杯直接倒到嗓子眼。

具体数值如下：

圆柱体积公式：
V = π * r² * h

设定值求另一个：
设定直径（D）为15mm（半径r=7.5mm），求高度（h）：
2.2 = 3.1416 * (0.75)² * h
h ≈ 2.2 / (3.1416 * 0.5625) ≈ 1.24 cm

尺寸：

内径： 15.0 mm

内高： 12.4 mm

I have a Bichon Frise named Tangtang, whose birthday is on July 9, 2025. Unfortunately, she caught a cold and started coughing yesterday because of the air conditioning. The veterinarian prescribed a medication called "Guogensu," a hepatic oral liquid, which requires a 2ml dose each time. Since I couldn’t find a suitable measuring container, I designed a small cup myself using the cylinder volume formula:
V = π * r² * h

To solve for one variable using the other:
Set the diameter (D) to 15mm (radius r = 7.5mm), and solve for the height (h):
2.2 = 3.1416 * (0.75)² * h
h ≈ 2.2 / (3.1416 * 0.5625) ≈ 1.24 cm

Dimensions:

Inner Diameter: 15.0 mm

Inner Height: 12.4 mm

Wall Thickness: 1.0 mm - 1.5 mm

The drawback of a cylindrical shape is that a small amount of liquid may remain at the flat bottom, making it difficult to pour out completely and resulting in measurement inaccuracies compared to a conical frustum. Therefore, I added an extra 0.2ml. After using it, I found it worked quite well and am sharing it for others who might need it.

There are two versions in total:

Ready to print directly.

A version with an embedded 8mm*2mm magnet.
