chebeHello readers! Last time I got my Adafruit HalloWing badge working with the SD Card Shield under Arduino. But that's a lot of naked electronics to have dangling around my neck. Let's make a case for it!
Someone already remixed the Hallowing badge case to fit a battery, so I had a go at remixing it further. I brought the model into Windows 3D Builder, cut, and extruded the depth of the case to 2cm. Which it turns out fits everything nicely! Except, the SD card is a bit squished against the edge of the case (you might need to put the SD card in after fitting the badge into the case). If I do this again next time I'd widen that bottom opening just a smidgen.
A slight hitch occurred when I brought the modified model into my slicer. It detected problems, and auto-fixed them for me. I couldn't see where the change had happened so I happily printed it up (in black PETG, in case you're curious). I found the issue afterwards. The slots at the top, through which to attach a lanyard, had been filled in. Never one to be deterred, I grabbed some heat-set inserts, a couple of M2.5 screws, and a scrap piece of leather. I cut the leather into a miniature saddle-bag shaped strap, punched two holes (turns out the smallest hole on my leather hole punch is 2.5mm), and put it all together. One nice thing about this arrangement is that it will work with two-clip lanyards (like Adafruit supply) and regular one-clip lanyards. Okay, all ready for the next event!
