Ergonaut One S Build Preparations

This guide will help you prepare all the necessary tools and materials for a successful Ergonaut One S build.

PCB

PCB is the core component of Ergonaut One S.

Tools:

You'd probably need:

  • Soldering iron;
  • Solder wire;
  • Flux;
  • Tweezers;
  • Isopropyl Alcohol or other suitable solvent for PCB cleaning;
  • Cotton Q-tips or other suitable material for PCB cleaning.

PCB Manufacturing

If you are brave enough, you can manufacture PCB yourself. But my suggestion would be to grab a Gerber archive from Github Releases and order PCBs from any capable PCB manufacturer, like:

You are free to choose any desirable PCB specification but keep in mind that all cases are modeled with 1.6mm PCB thickness in mind. You'd need two PCBs for one kit.

Case

The case is also an essential part of Ergonaut One S since it provides proper electrical insulation from the environment and provides reliable mounting plates for the switches.

You can choose to use one of three provided variants of the case:

Tools:

You'd probably need:

  • FDM 3D Printer or a friend with a printer;
  • [ONLY FOR CLASSIC CASE] Scalpel or some other cutting tool to remove included supports;
  • [OPTIONAL] Deburring tool.

BOM

You'd need some additional hardware to assemble your case:

Printing

Grab models here. Print with the following settings:

  • Layer height: 0.2mm;
  • Extrusion width: 0.4mm;
  • No support structures.

Note: Classic Case might require support structures if your printer either has no part cooling or bad part cooling.

Note: Please let the part cool off properly before removing it from build plate to reduce the risk of part warping

Choose your desired case variant (Classic or Modern) and print four parts:

  • Left Top;
  • Right Top (model should be mirrored by X axis in slicer);
  • Left Bottom;
  • Right Bottom (model should be mirrored by X axis in slicer).
