Last crawled date: 3 years ago
If you want the STLs of the latest improved version, detailed assembly pictures with texts and tips, my custom DuetWifi settings and macros, answers to your questions, access to online 3D view of the raw design with tools for viewing and measuring; then you can send me 25$ here: (https://www.paypal.me/RajaaKahel) and leave me a message with your email address.
Thank you.
Commercial use is not allowed.
keep an eye on the updates section in case I made an update so you remind me to send you the newer design.
Don't forget to give credit if you used this design or any part of it.
The free v1.0 version is no longer available.
This printer needs common engineering sense when assembling, especially for measurements, alignments, clearances/tolerances. Most holes intended to be processed after printing.
Don't use steel-core belts, they'll cause wrong print dimensions after a while.
Basic facts:
1-This printer is big, printing dimensions: (X430mm) (Y330mm) ( Z about 440mm)
2- It doesn't require priming towers or wiping.
3- Fast, as the parts are compact, light and solid.
4- Can have many tools as you need.
5- Easy spool mount that takes normal and big spools, it works as a filament dryer at the same time (from the printer heat).
6- Cheap to make comparing with the results and quality you get.
7- Made with love and passion :)
8- A tool changer beats any dual or other systems, it's much faster, much cleaner and gives unlimited options. It's the future!
9- Integrated 3D printed Z-probe which is smaller, lighter and more accurate than most common sensors (repeatability of less than 0.003mm. (check the video below).

Updates (for paid version):
-10/12/2018
Lowered the left belt 3mm for a better assembly (less parts, more compact and more accuracy) thus idlers mounts and X carriage are modified.
Optimized many parts for minimal support use when printing.
Modified the v6 mount to be able to take THE NIMBLE extruder or other stuff and some improvements.
Y carriages now have flush m3 screws.
21/12/2018
Some adjustments to the tool changer, Z motor mount and enclosure. Added magnetic door function.
13/1/2019 Added Nimble extruder adapter (lightest direct drive extruder available) and changed the Bowden guide design (no screws, snap it and slide it where you want).
15/1/2019 Changed the hotend mount design a bit for more strength when tightening the grip of the heatsink.
28/1/2019 Redesigned the electronics box.
12/6/2019 Designed a new part-cooling-shroud with integrated Z-probe which is smaller, lighter and more accurate than most common sensors. So now you have auto-leveling.
Also removed Z endstop.
4/9/2019 The parking brush holder is now adjustable (for fine height adjustment or longer nozzles like Volcano etc).
13/10/2019 Redesigned the belt locks for a stronger grip, simpler and more solid design.
13/07/2020 uploaded Simplify3D settings to Google Drive folder (for auto parking at the end of printing and other..).
