Model Description
3D model of 3dcentralva
The models were repaired and checked for printability.

The goal of this project is to enable the personal manufacturing of simple...Show more electronics, especially for Open Source Hardware -- with nothing except a 3D printer, your hands or equivalent, and the basic high-technology electronic components (capacitors, motors, transistors, etc -- but will eventually encompass ICs, microcontrollers etc). Instead of solder, wires, and breadboards, OpenSCAD generates a peg-board PCB and component holder, and a circuit can be hand-wound together with conductive thread.

This code base is intended to replace conventional etched PCBs, initially for very simple applications.

Tools and Materials
Currently, it has only been thoroughly tested on the MakerBot Replicator, with ABS plastic.

I also suggest some fine tweezers & tiny scissors, for circuit wrapping and placing components.

Programming was done in OpenSCAD.

You will also need to use the MCAD library

I have found success arranging the components in grids, in multiples of 'get_component_distance()', which is a standardized distance between pegs. Overlapping pegs between components allows you to save thread and time.

Print the parts with the standard replicator defaults or equivalent, with no raft and no support, in the proper orientation (as uploaded).

Alternatively, you can also place components free-hand. Either plot it out in OpenSCAD, or import the components in Blender -- but try to maintain roughly the same orientation for printing.

Primary feature set:
-- power components: by default only 1, but support for multiple in series --
battery_holder_AAA(count = 1)
battery_holder_AA(count = 1)
battery_holder_button_cell(count = 1)

-- component holders --
component_capacitor(diameter = 5.5)
component_LED(diameter = 5)
component_2_LEDs(diameter = 5)

-- and tie it all together --
base_board(length, width, thickness)
peg(peg_height = 5, slot_width = 0.8) // start and end point for traces
peg_cap() // end cap for peg, print separately
SPST_slide_switch_base() // base structure of slide switch (place this)
SPST_slide_switch_toggle() //sliding structure of switch, print separetly
trace_hop() //for when traces cross, give two separate channels at 90 degree angle

-- functions for placing: this is the distance between the center
of any component and their pegs. currently limited by width of slide switch --
get_component_distance() = 13.5
