MegaMAME

thingiverse

MegaMAME is a large console which can be stood on a table, or you can use the stand to hook it over your knees while sitting on the couch :-) I had to split the case into two parts to be able to print it on my Ender 6. I'm happy about how it turned out. The little hatch on the back makes it possible to change the micro-SD card in the Pi without disassembling the entire thing. Pliers are probably needed to do this in practice.. But it's probably a rare action anyway. It's assembled using two M6 threaded rods that run from left to right, and two 40mm M4 hex screw that go into existing threaded holes in the back of the display. The display is this: https://nl.aliexpress.com/item/32894885238.html Computer: Raspberry Pi 4 Model B (clone): https://nl.aliexpress.com/item/4000105144741.html Battery 12V 6600 mAh. I got it from a Dutch seller, but there are many suppliers, such as this one: https://www.delongbattery.com/Factory-Price-Rechargeable-18650-Lithium-Ion-12V-6600mAh-Li-Ion-Battery-Pack-for-LED-Light-Power-Tools-Batteries-pd43561705.html Charge connector: https://nl.aliexpress.com/item/33006101275.html, the 5.5 x 2.1 connector (item 4) USB voltage converter and distributor, to power both the Pi and the display over USB from the 12V battery: https://nl.aliexpress.com/item/32863274989.html Flat cables and connectors: from this page https://nl.aliexpress.com/item/4001289088224.html the following products: - black, 30cm ffc Cable - black, C2 Connector - black, 15cm ffc Cable - black, A1 Connector - Assembled Parts of, FFC -15cm - Assembled Parts of, Connector-D2 - Assembled Parts of, Connector-C2 You will also need: a male 5.5x2.1 connector to create the wire from the battery to the voltage controller, some flexible 2-strand wire for the power cable, some Blu-tack or similar to remove the small bit of play that the Pi has in its cavity. Also: a female 5.5 x 2.5 connector that connects the charge cable from the battery to the connector on the outside of the enclosure. The chromed copper hollow pipes are 12 mm outer diameter. I got these from the hardware store, in the bathroom department. For assembly: once all the electronics are in place, place the display at an angle above the Pi: then the flat cable connector just hooks over the Pi, and you can gently lower it. Keeping the longer flat cable in the space meant for it is a bit finicky.. In retrospect it would have been a good idea to have some velcro on this cable and inside the enclosure, so that it can stay down while the display is lowered. I used some electrical tape to stick the flatcable to the display, that also helped with this.
