[blwn](https://www.thingiverse.com/blwn/designs)'s [TM1638 case](https://www.thingiverse.com/thing:3578683) was very nearly perfect for my needs, but I desired a few changes. Fortunately, blwn's Thing provided a Fusion 360 export. **WARNING** TM1638 boards are not all the same. At the time of this posting, this case fits the TM1638 listing **mentioned above** but didn't fit another listing I ordered. **Notable changes** I needed to bring in power using a [barrel jack](https://www.amazon.com/gp/product/B07FK6MMGH) (or USB). I plan to several "Base" STL files, depending on where you want power ingress. Currently only the "Bottom" version is available. I wanted to use countersunk [m3 screws](https://www.amazon.com/gp/product/B07CYNKLT2) to affix the lid to the case, instead of glue or tape. I've remodeled the Lid and Base to attach using four m3 screws (12mm is about perfect). The original model used m3 heat inserts, but my m3 heat inserts didn't fit. I've moved the heat-inserts to the Base. It is re-designed to use [these m3 heat inserts](https://www.amazon.com/gp/product/B08BJD3W4X). I wanted stand-offs to be able to use an [ElectroCookie Mini PCB Prototype Board](https://www.amazon.com/gp/product/B081MSKJJX). The screws for attaching the PCB to the standoffs are two [m2.5 screws](https://www.amazon.com/gp/product/B07CLQFQ4C) (5mm is about perfect). I've included a Fusion 360 Export for anyone who want to to remix it using Fusion 360. It uses an embedded model (the PCB standoffs), but I imagine the export accounts for that.
