Radiomaster Ranger Micro Case + Lid for the old PCB

thingiverse

### Motivation I wanted to reuse my old PCB in a new enclosure so that I have two Ranger Micros and I can sell the "good new one" with the fixed XT30 bug, cause who needs the XT30 anyway. ### Note Upon seeing some misunderstanding: Please DO NOT use the variant with the XT30 hole in it, unless you are using this case for one of the newer PCBs (V1.6 and higher). If you use it with an older PCB, choose one with a blocked or desoldered XT30. ### Variants - Case - `case normal.stl` is if the uncasing of the old PCB went fine - `case with pin protection.stl` is if, just like on mine, the pin protection broke off (because it's glued) while taking out the old PCB from the original case. **Do not use "with pin protection" just because it sounds nicer.** - Lid - `lid.stl` if you desoldered the XT30 - `lid xt30.stl` if you need the XT30 cutout, that is, if you are encasing a newer V1.6 PCB with the fix implemented - `lid xt30_covered.stl` if you are lazy and don't want to desolder the XT30 but still want to block it from being used - If you are messing with the NX source files: All 5 variants can be created by enabling or disabling certain steps in the navigator from the 2 source files. ### Design The design is almost an exact replica of the original, thus you want a fan and need an SMA adapter/antenna. The only modifications are that the XT30 hole is no longer there and the cooling vents are larger due to 3D printing tolerances. .prt files are for Siemens NX and maybe some other programs if they can import them. ### Lithophane I embedded the Radiomaster logo as a lithophane for the status LED. This does a reasonably good job of diffusing as well as letting light pass, at least with my (random brand that even I don't know) filament. If you use a straight SMA plug, the wire will partly block the lithophane. This obviously doesn't affect functionality, but won't look as nice. Thanks to vm3d for finding some cheaper angled plugs, though (at least with shipping to Germany) straight is still cheaper. ### Other needed parts - M2 screws for PCB, fan and lid, I think all slots can take M2x4 and M2x5, but not all can take M2x6. Additionally, you need 2 M2 washers. - Fan: - [This fan works and is brushless](https://de.aliexpress.com/item/1005003383969472.html), but has the wrong plug and it comes in a pack of two. - [This fan is slightly cheaper](https://www.aliexpress.com/item/1005003690094711.html) but it is unknown whether it is brushless or brushed. Might be louder. It also has the wrong plug. - If you want another one, search for one that is 20x20x6, or 2006 size respectively. - A 2 pin JST plug (1.25mm) for the fan - Antenna and SMA adapter: - [Cheapest Antenna + SMA Adapter I found](https://de.aliexpress.com/item/1005004774834873.html), but it conflicts with the space in some radios like the TX16. I would instead choose an SMA adapter and proper T or Moxon antenna combination like the following: - [Happymodel Moxon antenna](https://de.aliexpress.com/item/1005003690087542.html), the Moxon is directional. - [Happymodel Omni antenna](https://www.aliexpress.com/item/1005002476562349.html) - [IPEX to SMA Adapter](https://de.aliexpress.com/item/32806195194.html) Choose 7 or 10cm, depending on your liking. Choose SMA or RPSMA depending on the antenna you choose. 1.13 cable is more bendable than 316, so I would choose the former. - Angled plug, slightly more expensive [1](https://www.aliexpress.com/item/1005004698616302.html) or [2](https://www.aliexpress.com/item/1005004949007838.html)
