LCD 1602 Housing - Remix

LCD 1602 Housing - Remix This is a remix of... LCD 1602 Housing https://www.thingiverse.com/thing:2487321 ...originally posted by... mitpro, on August 17, 2017. I believe his post is also a remix from an even earlier posting. I like the basic design of the box very much. It caught my eye right away when searching for an enclosure for a 1602 LCD display project but I found it too shallow for my purpose. I've included files for several options modifying the original design including a deeper box, radiused edges, provisions for an Arduino Nano within the box and a strongback for fastening the display to the underside of the cover. I've also added provisions for threaded brass inserts for the cover/box screws. Box (2 options): Option A: A file for an extended height box (~ 16 mm internal height) with the corner screw holes modified for M3 threaded brass inserts and with radiuses on the bottom edges, otherwise identical to the original design. Option B: A file with the above changes plus screw posts for an Arduino Nano and a rectangular hole in the end for access to the USB port on the Arduino. That port can be used to power the project and/or upload to the Nano. NOTE: The photo of the box shows an additional structure at the bottom of the box cavity for retaining an additional small circuit board and a 3.5 mm audio jack in the end. Those features are not in either of the box STL files. Cover: A cover for use with Option D, below, with... - Radiused outside edges - A tab on the inside the same height as the backlight tab on the 1602 so the display sits level - A bevel around the rectangular display hole - Two holes with counterbored screw head pockets for M2 screws (with flat washers) to engage the strongback (see below), clamping the display to the underside of the cover Strongback (2 options): Option C: A plain strongback for holding the display to the underside of the cover, intended to be glued to the bottom of the OP's original cover. Option D: A strongback slightly longer than Option C (but still fits within the box) with holes for M2 brass threaded inserts, intended to be used with the remixed cover described above. NOTES: The threaded brass inserts in the box base and the strongback should not need to be heat set. The box inserts can be drawn in with a long screw; the strongback inserts can be pressed in with a vise or clamp. If using a Nano, I recommend using a 1 mm drill to clear the four mounting screw holes to clean them out, then driving the screws in before mounting the Nano to pre-cut the threads in the plastic. Wrestling with the Nano with wires attached is difficult enough without dealing with tight screw holes at the same time. Materials: For the Box: 4 X M3 threaded brass inserts 4 X M3 X 15 mm (or longer) machine screws 4 X M3 flat washer For the Option D Strongback: 2 X M2 threaded brass inserts 2 X M2 flat washer 2 X M2 X 10 mm button or Allen head machine screw For Nano Mounting, Option B: 4 X M1.4 X 6 mm self tapping screws
