K150 Pic Programmer Case

thingiverse

This is a case designed specifically for use with a PIC chip K150 usb programmer. I created this project for my board, which was manufactured by Baite and features a mini USB connector that serves as both a power source and communication port. The build itself is straightforward, with cutouts made to accommodate necessary connections. The LED on this unit is surface-mounted, so I drilled a hole to insert an acrylic rod. This type of rod can be purchased from Amazon at the following link: https://www.amazon.com/gp/product/B0006O6QYO/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1. The rod is 1/8 inch in diameter, which fits perfectly within a 3.5mm hole. I inserted the rod until it rested on top of the LED and then trimmed it slightly above the surface of the case using progressively finer grits of sandpaper. Both ends were polished to create a smooth finish before being glued into place. As shown in the photo with the cable attached, this setup works flawlessly. The lettering is recessed 0.5mm, which I then hand-painted black. To achieve this look, you could also use multi-material printing instead of painting. The holes at the bottom and corresponding pegs on top are designed to accommodate a #4 1/2 inch flat head metal screw. Due to the coarse threads on the screw, no matching threads need to be printed in the case.
