mkbd65 case
|
|
===========
|
|
|
|
_The case and key set for mkbd65 is still a work in progress!_
|
|
|
|
This is the case for mkbd65. It is build using [OpenSCAD][openscad] to be able to generate multiple cases fitting
|
|
different phones from a single file.
|
|
Follow the guide at https://mkbd65.xengi.de to build a case for your phone.
|
|
|
|
## Generate a case
|
|
|
|
Edit the file `main.scad` and import your phones scad file from the `lib/` folder. If your phone is not in there it's
|
|
not supported yet. Please open a ticket or join the #mkbd65 channel on hackint via IRC or Matrix and ask for support.
|
|
Adding support for a new phone is pretty easy as long as some requirements are met.
|
|
|
|
If your phone is supported and you have edited the file, run this command to generate the 3MF and STL files for your 3D
|
|
printers slicer software. You can use whatever material you like. PLA has proven to be easy to print and working well
|
|
for the case.
|
|
|
|
```shell
|
|
make main
|
|
```
|
|
|
|
## Generate a key set
|
|
|
|
To generate the key set you can either use a predefined layout or generate your own. There are two predefined layouts
|
|
for English US International and German. You can generate the 3D files for them with the following commands:
|
|
|
|
```shell
|
|
make keys_en-us-intl
|
|
make keys_de
|
|
```
|
|
|
|
This will generate the neccessary 3MF and STL files that you can use for your 3D printers slicer software. I recommend a
|
|
flexible filament like Filaflex 95A for the best typing experience.
|
|
|
|
### Custom layout
|
|
|
|
If you want to build your own custom layout follow the instruction in the file `custom_keyset.scad`. It will explain how
|
|
to write the openscad code for a key set and generate the 3MF and STL files. You can use any of the keys from a 5x14
|
|
matrix and also combine them however you like. Remember that you have to duplicate the keys in the config of the QMK
|
|
software for every non 1x1 key too. Because electrically every switch is still a single unique key and gets detected as
|
|
such.
|
|
|
|
So if you want to create a 3x1 space bar at position (0, 5) you can create a key cap by using `key(x=0, y=5, w=3)`. In
|
|
the QMK config you have to create 3 distinct space bar keys next to each other.
|
|
|
|
In theory the maximum width of a key is 3. You can use more then that but the key will get sliced at different points to
|
|
avoid accidental duble presses of the switches underneath.

Generate CAD files
|
|
------------------
|
|
|
|
1. Install dependencies
|
|
```shell
|
|
pip3 install --user -r requirements.txt
|
|
```
|
|
2. Generate files for your phone for example the Oneplus 8T
|
|
```shell
|
|
./mkbd65.py --layout=ansi --3mf oneplus_8t.ini
|
|
```
|
|
|
|
Build instructions
|
|
------------------
|
|
|
|
### 3D printing
|
|
|
|
Most of the case can be 3D printed using a home 3D printer, any online 3D printing service or at your local hack/make space. You can find your local hack/make space [here](https://wiki.hackerspaces.org/List_of_Hacker_Spaces).
|
|
|
|
Print out these files with a sturdy filament like PLA:
|
|
|
|
- `lower_case`
|
|
|
|
Print out the `key_mat` with a flexible filament like [FilaFlexible40](https://fila-tech.store/product/filaflexible40).
|
|
|
|
Config files
|
|
------------
|
|
|
|
Properties for different phones are saved in INI files. Currently the only file included is `oneplus_8t.ini` for the
|
|
Oneplus 8T phone. You can add your one phone by providing the INI file with measurements and a file describing it's camera bump.
|
|
|
|
In the config file you can define the phones size but also other aspects like the used font for the key mat. Here is a list of
|
|
the possile options:
|
|
|
|
| Group | Option | Type | Default | Description |
|
|
| ------- | --------- | ------ | ---------------------- | ----------------------------- |
|
|
| keymap | thickness | Number | 0.5 | Thickness of the keymap in mm |
|
|
| key_mat | thickness | Number | 1 | Thickness of the key in mm |
|
|
| | font | String | DejaVu Sans:style=Bold | Font used for labels |
|
|
|
|
OpenSCAD files
|
|
--------------
|
|
|
|
The generator script will create multiple files.
|
|
|
|
| File | Material | Description |
|
|
|------------------------| -------- | -------------------------------------- |
|
|
| mkbd65_key_mat.scad | TPU | 3D printable |
|
|
| mkbd65_pcb.scad | - | Just a spacer for the 3D model fitting |
|
|
| mkbd65_top_plate.scad | Acrylic | Laser cut on a CNC |
|
|
| mkbd65_lower_case.scad | PLA | 3D printable |
|
|
| mkbd65_internals.scad | PLA | 3D printable |
|
|
| mkbd65.scad | - | Combination of the above files |
