A simple customizable enclosure for my small ESP projects. Written in openscad, more to come.
I use it for Bluethooth (BLE) to Home Assistant gateways/proxis with ESPHome. Currently working on using OpenMQTTgateway to support the RF modules.
#Examples
| ESP8266 | ESP32-S2 | ESP32-C3 |
|---|---|---|
 |
 |
 |
| ESP32 | ESP32 with screws | a pressfit Cover |
|---|---|---|
 |
 |
 |
| ESP32 with with space for antenna (better receive range BLE proxy) | Using an antenna from an old Fritzbox or similar 2.4 Ghz antennas do increase the range a lot. |
|---|---|

 |
| ESP32 with with radios like CC1101 or RFM69 | |

Find the pictures in directory PNG, the 3D models in STL.
I printed with PLA, 50% infill.
You can choose that it uses screws (2mm self tabbing) or just holds the lid by press fit (works very nice here with my Ender 3 V2). RF modules can be selected (two of each with own placing). Flavours of the ESP Mini D1 module can be selected.
There might be combinations of parameters that do not fit together.
- D1MiniEnclusure.scad The box creator, includes the other scad files.
- RfModules.scad Defines sizes and models for rf modules like RMF69, CC1101
- EspModules.json Defines sizes and models for flavours of Mini D1 (Esp8866, Esp32, ..)
- Makefile The control file for make (I use gmake, others not tested).
- svn_rev.scad Contains the subversion revision and is automatically created by the Makefile and SubWCRev (subwcrev). The revision string gets printed inside the enclosure.
On Linux open a shell in the source directory, then type make and wait.
The png and stl files will get created. This takes a while, so be patient.
On Windows, Mac, your are on your own.
A manual rebuild with openscad is also possible, open D1MiniEnclusure.scad in openscad, select a thing in the customizer (PrintThis),
press F6, wait, then F7 to export the stl.
To much work for me, therefore I created the Makefile.
It parses the json file to get the list of things/flavours to build.
Then it creates pictures in PNG directory and the stl in STL.
It also checks for a template file (svn_rev.tmpl) and calls SubWCRev to create svn_rev.scad.
I do not provide the template file, so this rule will not execute on your machine
(I provide the svn_rev.scad instead).
You might also notice that it checks for my library dfLibscad. If found, the libraries tmpl file gets translated into
another scad file with a version string of the library.
I use this Makefile in other projects as well, just the very few first lines need to be adjusted.
Feel free to reuse it.
