Smartbox Case Latch

Replacement latch for a Pelican style case used by SmartBox for their key programming system.

I believe the brand is actually HUL but it has no identifying marks.

Seems they make a lot of drone carrier boxes as well so I hope others can make use of it.

Drive the metal pins out with a pin punch, awl, skinny screwdriver, whatever then drive the second shorter pin out the same way. I find a slightly open bench vise to be a perfect place to do this.

Reverse the process with the new part. The vise is a great way to drive the smaller pin back in again. I had no problems driving the pin into the printed part.

Part is oriented for maximum strength supports will be needed.

Mine is an okay fit but if I were to reprint them I'd probably reduce the length by a milimeter or two to make it a bit tighter.

Only post-processing was removing the infill.

How I Designed This

Scanned the item on a flatbed scanner with a backlight.

Edited the outline to clean up a bit and give it good contrast.

Imported and scanned bitmap with Inkscape to create an SVG.

Imported SVG into Tinkercad and extruded, scaled and converted to its final 3d shape.

Sliced in Cura and printed at 100% infill.
