Drok LD25 USB Load Module Case

Case and knob for the Drok USB 25w load module.

The bottom is solid (to protect the electronics) since the heat is extracted from the MOSFETs via the fan/heatsink. A small fan grill was added to keep fingers out of the fan-blades.

Remove the pc-board's pressed in standoff-feet and mount it into the case-bottom with (4) 2mm x 4mm self-tapping screws.

The case-top is mounted to the fan/heatsink using (4) 2.5mm x 16mm machine screws (remove the two original shorter screws). The case-top legs press-fit into small cutouts in the base.

The knob is just a press fit over the potentiometer shaft.

I have included the Fusion f3d file if you want to modify the basic design.

3/28/2025: Added DrokTopClosedFace stl for a version that inserts a wall across the front of the fan shroud on the LED side. Also re-uploaded the open-faced version as the previous one was an old version that still included a *wrongly* placed wall... Thanks "objecttothis" for finding the error!
