HT1621 7 segment LCD case
Description
This is a case for the HT1621, 7 segment LCD's, Sold in the uk by Hoby Components for just £3.99. https://hobbycomponents.com/newproducts/1001-ht1621-6-digit-7-segment-lcd-module The hobby components web site has a forum with the arduino code on it to make using these displays easy, i used one of them for a thermometer display and another a clock. The case is the shape it is (longer on one side) due to the connectors on the back of the lcd module that stick out the side of it, this version is plug and play, so the hole in the back allows the 6 wires that are plugged into the header pins to exit and be connected to your arduino, (I made another version that is shorter and more symmetrical, but you need to de-solder or cut the header pins and solder on a 6 core wire for that version) There are 2 versions of this case: The 'Case no mount' is a flat case, allowing you to place it on any surface, but it is not fixed down (unless you use say double sided tape) The 'Case with mounting lug' is used with the 'Mounting foot' and allows you to screw the foot to something, and have the case mount on that foot. The 'Back' is the part that..erm, is used as the back. The LCD module is sandwiched between the case and back and 4 screws go through all 3 parts (case, pcb and back) The pillars inside the case have M3 threads in them, and the back has clearance holes to hide the heads of M3 x 8mm cap head allen bolts. The foot... if you decide to print the 'case with mounting lug' version, takes an M4 x 16mm bolt and M4 nut for the connection between the case and foot, again recesses are present to accept the M4 nut and hold it in place, and hide most of the bolt head. And the foot has 4 screw down holes, sized to take M4 allen head bolts, but self tapping screws can be used if you wish. Apologies for the rubbish photo of the case in use, i got a strand of filament stuck under it when it printed, and i printed this one at .30mm layer height as i was working on getting the design right. i also made a smaller version of this case, but that needs a different connection method: https://www.thingiverse.com/thing:4742570
