Lets Split and Levinson Keeb.io case middle layer

thingiverse

I designed a custom Lets Split enclosure several months ago, utilizing Keeb.io's aluminum Lets Split case along with an acrylic middle layer. Over time, however, its appearance began to show signs of wear and tear. I had previously encountered frosted acrylic layers that produced an excellent look while eliminating glare, so I set out to recreate this effect using a PLA shell in the same design. To achieve a neat pattern, I selected a specific infill pattern and density during my print. By recreating the original acrylic piece from my previous build, I was able to address several issues with the design of the original product. Firstly, the cutout around the I/O ports now better accommodates the shape of the PCB itself. The original acrylic did not fit past the edge near the USB-C port and required modifications to accommodate it. This updated design provides more room, ensuring a proper fit for any Lets Split. The second problem I addressed was the original case and layer's use of 12mm brass standoffs to support the promicro of a standard Lets Split. The acrylic middle layer in my previous build consisted of two pieces: one thick piece measuring 9.5 mm and another 2.0 mm. This resulted in 0.5 mm of the standoffs extending beyond, along with a noticeable refractive line where the two pieces meet.
