Ugh, this was exhausting! Let me jot down the must-read notes first.

1. Adjust tolerances according to your printer model.

2. If you want to burn incense, avoid PLA and use ABS instead—PLA can catch fire (the author nearly had a fire in their dormitory).

3. If you only have PLA but still wish to achieve the flowing‑incense effect, follow these steps: 1) Ensure good ventilation; 2) Use an iron spacer; 3) Burn the incense outside the burner until the flow becomes visible, then place it inside the structure (this reduces heat exposure); 4) While admiring the effect, test the temperature with your hand—if the roof feels too hot, remove it immediately to dissipate heat (otherwise, the material may melt and collapse); 5) When about one-third of the incense remains, quickly take it out to prevent the base material from deforming due to overheating.

4. Manual coloring is recommended.

5. For added stability, apply 502 glue.

6. That pile of white parts doesn’t necessarily need to be painted—just ensure adequate heat dissipation (add arched eyelets if desired, or leave them as is if they’re unsightly).

-----Some random musings below----

I’m really worn out after all this work. This time, the architectural prototype is based on the narrative mural from Cave 217 at Dunhuang—I genuinely love this mural. The dougong brackets were hand‑colored using pigments I personally selected; my child couldn’t afford Ams’s paints. Both the beams and ridgepole were painted green (yellow would also work—I followed the mural’s color scheme). The “seven reds and eight whites” pattern was recreated using circular dots—a technique seen in both the mural and the surviving example at Nanchan Temple’s main hall. (Though I didn’t see such dots when visiting Nanchan Temple, rumors suggest they do exist.) As for the swallow‑tail panels, you can either paint them or manually swap in black material; the rafter ends can be left white. Of course, if you’d rather cut corners—ahem, prefer plain wood—you can skip painting altogether. Overall, the structure is built to withstand wear and tear (after all, I’m not constructing any interior components—hahaha!).
