An Introduction to Atlas

The Atlas variant of the Ender 3 and Ender 3 V2 is an industrial style bed slinger, optimized for reliability and compatibility. The goal is to create a printer that brings together the sturdy design of the VORON Switchwire and the flexibility of a toolchanger.
The MK1 version increases the stability of the basic frame, adds multiple drawers and replaces the stock bowden extruder and toolhead with the custom Atlas toolhead and Creality E-Fit extruder. Currently the toolhead is mounted directly to the v-roller plate, in future versions this will be replaced with a quick changing system and the Ender 3 S1 breakout board. The current Atlas version improves the part cooling capability of the printer with dual 5015 blower fans, angled on eather side of the toolhead, similar to the setup of the Ender 7, adds cable chains for all axis and moves the spool holder to the middle of the top 20x20 extrusion. Additionally the Atlas toolhead is compatible with all drop in replacements for the stock hotend (this includes the Ender REVO, Dragonfly, Voron and Spider (V1-V3) hotend) and BL Touch and CR Touch.

!!!Please not that all the parts in the linked collection are not my own creation and i simply gathered them here for easier printing and project overview. I do not own any of these designs, they belong to the people, who uploaded them. The Atlas toolhead is a remix, the sources can be found under the remix section!!!

Needed parts and how to print them

All the parts that need to be printed for the toolhead can be found here under the downloads tap. For all other printed parts visit: https://www.thingiverse.com/xxxmorpheusxxx/collections/42594693/things
All parts need to be printed with the values shown under the Printer Settings tap.
Additional to the printed parts you will also need:

add bill of materials

Toolhead:
2x M3x16mm bolt
3x M3x8mm bolt
3x M3 washer
1x Creality E-Fit extruder
1x Creality 40-32 steppermotor (the 40-32 from the x-axis can be reused, if you swap it out with the original 42-40 extruder motor)
1x PTFE tube 10cm (needs to be cut to length)
2x 5015 blower fan 24V
1x 4010 axial fan 24V (can be reused from the old toolhead)
2x JST-SM crimp connectors (male and female) + crimping tool
1x BL Touch or CR Touch + cable

Frame stabilizer:
2x M10x470 mm threaded rod (recommended 10x1000mm, cut in half)
8x M10 nut
8x M10 washer
6x M5x30 bolt
2x M5x25 bolt
4x M5x10 bolt
10x M5 t-nut
12x M5 washer
M5 tap and die (for the 2 edges of the top v slot profile)

Side drawer:
2x M4x5mm bolt
2x M4 t-nut

Mainboard fans:
2x 4010 axial fan 24V

Future plans

The MK2 version of Atlas will introduce linear rails for all axis with custom 3d printable brackets, a bracket for a reverse bowden setup and by that compatibility to a filament drybox and a Prusa MMU and a filament sensor.

The MK3 version will build the Ender 3 S1 breakout board into the toolhead to create an easy toolchanging system this will make the Atlas compatible with laser and CNC modules up to 10 Watts. Furthermore the MK3 will introduce a heated chamber, controlled by an onboard microcontroller, that can be screwed onto the printer and can be removed easily, in order to print PLA as well as ABS, ASA and other materials that need to be filtered.

Any version will be compatible with the Creality sonic pad or the Klipper conversion via a Raspberry pi, an upgrade that is highly recommended to gain quality, speed and network compatibility.
