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.

SIMINPUT BoxBoard PCB1Or whatever the hell you want to use
M2x4mm screw16Modules
M3 screw86-12mm length needed for the front 4 screws
M2x2 insert, 3.2 OD16One per M2 screw
M3x6 insert, 4.5 OD8One per M3 screw
Soldering iron1Solders joints and sets the inserts
GlueOnly for the table clamp
Rubber pads or rubber rollOnly 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

Two-Slot Rotary Switch Module

PartQtyNotes
Small 8-way rotary switch1Aliexpress 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.

Wiring

PartQtyNotes
JST 1.25mm 2 pin cable1 per inputSold 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.

The Aliexpress links are examples rather than requirements. Anything with the same dimensions works. If you find a better source, post it on the Discord.
