Carry Handles are great, but how do you mount them to the main board? With a mounting lug, of course! This simple little design is a little bit more than just a simple block with some holes in it. Not only does the lug need to be strong enough to hold the weight of the lab, but it also needs to be designed to allow the handle to snap on and off. To satisfy the first goal, I couldn’t deny the strength of good old fashioned metal. The lug has two holes for M6 bolts (which I just so happened to have handy since that’s the size of rack mount screws I use) to pass through the lug and bite into receiving aluminum nuts that pass through the board. Hitting the second goal meant that I needed the lug to allow a slide on/off design leading to the taper you see in the model.
The taper turned out to be pretty important because it allows the handle to slide and clip on without needing double the length of the mounting lug open inside the handle. The lug is also angled inward from front to back which serves to “pull” the handle tight against the board when mounted leading to a stronger overall connection. This angle also prevents the handle from just slipping off vertically.
The design itself was pretty simple, but I did have to noodle a bit on how to get the taper and the angle just right. Like most other things, it took a few prototypes to get it right… and I realized during prototyping that my original goal of creating two lugs and making a U-shaped handle. Just wouldn’t work because of the bolt heads on the back of the board interfering. So, we’re just gonna have to YOLO it with a single lug in the center of the board!
