A precision-engineered, clean, and durable protective case designed specifically for the popular 200W 15A DC-DC Step-Down Buck Converter Module (8-60V input, 1-36V output).
The case provides full component protection, clean cable routing, and secure PCB mounting while remaining fast and easy to print without any supports.

Flush Top Finish: Wall height aligns with the top of the aluminum heatsink for optimal component protection and heat dissipation.
Zero Supports Needed: Designed specifically for FDM 3D printing without any support material.
