This is a mold for making spinning top from PLA filament purge. The tops made with this mold are very colorful and spin well. I printed the mold with PETG at 100% infill and did not need to use supports (PC might work even better).

What you will need:

• An unused oven

• A silicone mat (it's easier to flip and roll the melted PLA into a ball on a silicone mat than on a metal baking tray)
• PLA filament purge
• A 3M respirator or N95 mask (the fumes from melting PLA in the oven are stronger, so please protect yourself)
• Work gloves
• Tongs
• Pliers
• A digital scale

Process：

1. Accurately weigh 6g of PLA filament purge and place it in the oven.Preheat the oven to 200-230°C and heat the filament purge for approximately 5 minutes.

2. Use tongs and pliers to shape the melted PLA into a ball. Evenly folded patterns will look better.

3. Place the shaped plastic into the mold and press the mold firmly.

4. After approximately 3 minutes, open the mold and remove the top. If the top is difficult to remove, use pliers to take it out.

这是一个使用PLA耗材废料制作陀螺的模具，制作出的陀螺颜色比较漂亮，旋转的很好。我用PETG 100%填充来打印模具，无需添加支撑（PC可能效果会更好）。

你需要：一个闲置的烤箱，一个硅胶垫（需要把熔化的PLA翻折并团成一团，这在金属烤盘中很难操作），PLA耗材废料，3M防毒面具或N95口罩（在烤箱中熔化PLA产生的气味更大，请做好防护），工作手套，取盘夹，钳子，电子秤。

压模步骤：

1，将 6g（请准确称重）PLA耗材废料放入烤箱中，200～230℃加热约5分钟（烤箱需预热）

2，用取盘夹和钳子把熔化的PLA团成一团（翻折均匀的纹理会更漂亮）

3，把团好的塑料放入模具中，用力挤压模具。

4，大约3分钟以后打开模具取出陀螺。如果脱模困难可以用钳子把陀螺取出。
