25 Yuan Ultra-Low Cost Heating Table

Important Notice: The price is only a hard cost reference price and does not include shipping. Please consider whether you want to replicate it yourself. Since I only did this project because I happened to have the materials on hand, and shipping costs across the country are even higher, I suggest calculating the total price including shipping according to the table before deciding whether to replicate it. This is just to provide an idea; I won't make a penny from shipping costs. This is an open-source project, so keyboard warriors please turn left.
 
Urgent Reminder: The size of the Deer Fairy 300W heating plate I bought was 75*63mm, with a hole spacing of 60*53.5. The new model seems to have been redesigned, with a hole spacing of 66*53.5. The attached file shows the version with a hole spacing of 66; please check the hole spacing of your purchased PTC.
 
A super low-cost desoldering heating table is released, with an estimated cost exceeding 25 yuan (excluding printed parts). As we all know, beauty comes at a price... Ultimate Lite version.
Functions:
1. Blue light when powered on, no heating.
2. Press the button to start heating; automatically shuts off after 10 minutes of heating to avoid accidents caused by forgetting to turn it off (a lesson learned the hard way).
3. Press the button to turn off heating and turn on the fan for rapid cooling.
4. All supports and circuit boards can be obtained in one pass, saving JLCPCB money (most other systems currently require four passes).
5. The heating plate is surrounded by a PCB to prevent burns when adjusting components (a lesson learned the hard way).
