LM2596 case for Ender 3

thingiverse

This setup is ideal for two LM2596 (a widely popular step-down regulator) to be installed inside the Ender 3 - near the main board. The plan was to utilize one regulator for the motherboard fan and another for the hotend fan, which can also serve as a replacement fan requiring lower voltage instead of 24V. Two primary bolts are 4mm long and used with T-nuts (for frame mounting), while four smaller bolts measure about 5mm in length (without heads) and have a width of 2.5mm.
