Parts and hardware
Everything a full build uses, per assembly. Kits arrive with all of it, so read this as a checklist or as a shopping list if you are starting from nothing.
Main enclosure
Milo's list from the Printables post, unchanged. The electronics line is deliberately loose: nothing about the enclosure forces you to use my board.
| Part | Qty | Notes |
|---|---|---|
| SIMINPUT BoxBoard PCB | 1 | Or whatever the hell you want to use |
| M2x4mm screw | 16 | Modules |
| M3 screw | 8 | 6-12mm length needed for the front 4 screws |
| M2x2 insert, 3.2 OD | 16 | One per M2 screw |
| M3x6 insert, 4.5 OD | 8 | One per M3 screw |
| Soldering iron | 1 | Solders joints and sets the inserts |
| Glue | Only for the table clamp | |
| Rubber pads or rubber roll | Only for the table clamp |
The outer diameter of the inserts is easily changed in CAD. You need one insert per screw.
Dual-Position Module
No particular parts are required, use anything you wish. The holes are 12mm with threaded adapters for common sizes (6mm and 7mm). If you need a different size, change the perimeters in CAD, or ask me on Discord.
Rotary Module
| Part | Qty | Notes |
|---|---|---|
| Small 8-way rotary switch | 1 | Aliexpress example, first five positions wired |
Two-Slot Rotary Switch Module
| Part | Qty | Notes |
|---|---|---|
| Small 8-way rotary switch | 1 | Aliexpress example, all eight positions wired |
Same switch as the single-slot rotary. The printed housing is the part that differs: it is two slots wide and comes with its own knob.
Key module
| Part | Qty | Notes |
|---|---|---|
| 8x8mm keys | 3 | Aliexpress example, select 8x8 |
| Lubricant | Not required | |
| Hot glue | Holds the keys in the housing |
Lever module
| Part | Qty | Notes |
|---|---|---|
| 5x6 ball spring | 1 | Aliexpress example |
| Micro-switch, minimum 11mm handle | 2 | Standard 12.8*7.3mm |
| M3 screw | 1 | 6-8mm length |
| M2 screw | 4 | 6-9mm length |
| M3x6 insert, 4.5 OD | 1 | |
| M2x2 insert, 3.2 OD | 4 | |
| Lubricant | Any | |
| Hot glue | For the micro switches |
Guarded switch module
| Part | Qty | Notes |
|---|---|---|
| Cover including switch | 1 | Any similar guard cover works |
| Loose cover | 1 | Alternative, use with your own switch |
Wiring
| Part | Qty | Notes |
|---|---|---|
| JST 1.25mm 2 pin cable | 1 per input | Sold in 25-packs on the store, capped at two packs per board |
How many inputs a control uses is on the soldering and wiring page. A 3-way switch and an encoder each take two, a rotary takes one per position minus one, and everything else takes one.
