MK3S Extruder for Mosquito Hotend and MMU2S

This is a remix of the BMG clone made by Marco Zambon slightly adapted to be used with a Mosquito Hotend.

Also there is a special cover and lever to be used with the new IR sensor and MMU2S. If you don't use MMU2 take the lever from the Marco Zambon thing: https://www.thingiverse.com/thing:3553064.

Note: if you are using an E3D V6 and MMU2 my sensor cover and lever can be used with Marco Zambon extruder and the V6 hotend.

A good X-Axis to be used with this extruder is: https://www.thingiverse.com/thing:3559732.

You need:

To use this extruder with Mosquito hotend you need to print all the stl (choose only one cover) included here and:

1. The provided adaptor v6 to Mosquito (print it without supports).
2. A PTFE tube of 22.35mm length (I'm using it not chamfered).
3. An additional M3x16 screw to secure below part of extruder better, a new screw hole has been added.

Optional:

If you need a Silicone sock I have used these links: https://www.thingiverse.com/thing:3562134 and https://www.thingiverse.com/thing:3670108 to make one myself.

Updates:

2019/05/28:

Added my own V6 to Mosquito adaptor, it can be printed without supports.

2019/05/29:

Improved MMU2 covers, lever and fan shroud.

2019/05/31:

• Added a new extruder body, the IR hole has been removed to improve the filament path. Only to be used with MMU2S.

• The sensor cover now has two parts to fine tune the IR sensor position relative to the lever, with a bolt (M3x5) to secure it.

• Added a sensor cover to use PC4-M10, the other is compatible with the Prusa one, PC4-M5.

• Added a IR sensor cover with hole for the LED mod (I have used this 3mm LED: https://www.amazon.com/LAOMAO-Bulbs-Orange-Pre-Wired-Parties/dp/B06Y26RSL1/ref=sr_1_1?keywords=LAOMAO+1+Pack+%2820+Bulbs%29+3mm+12V+DC+Orange+LED+Pre-Wired+Round+Top+Bulb+Lamp+For+DIY+Car+Boat+Toys+Parties&qid=1559319836&s=gateway&sr=8-1)

• Added a hole for zip tie on back sensor cover to secure the IR sensor cable.

• Added a nub to V6 Mosquito adaptor to prevent twists better (the nub has to face towards mosquito logo), so nozzles can be changed with one hand.

• New Extruder front with the nub hole (changed the text to BMG).

2019/06/02:

Improved MMU2S sensor cover and IR cover.

2019/06/03:

• Changed the thread insert by a square nut.
• Improved slighly the filament path on MMU2 extruder body.
• Recovered the original shape of extruder front to use other fan ducts.

2019/06/05:

• Improved fan shroud
• Added an improved blower fan arm

2019/06/12:

• Improved Extruder Front to prevent Mosquito Extruder oscillate vertically.
  Please download and print this file as soon as possible if you are using this extruder.

2019/06/13:

• Added square nuts for the sensor cover (only MMU2 body) and custom support.

2019/06/14:

• Added a new MMU2S extruder body, the PTFE tube inserts to bondtech gears. You need a PTFE tube 17mm longer.
• Added X Carrriage for MMU2S bodies.

2019/07/30:

Improved slightly the MMU2 sensor covers.

2019/08/31:

Added a zip file with a small modification on front to be used with my Zaribo Linear Rails 15x15: https://www.thingiverse.com/thing:3835170

2019/09/01:

1. Added a square nut to secure better the up_sensor parts.
2. Improved the IR covers.

2019/10/14:

Modified front and body files (I have appened the v2 suffix):

1. Added a square nut (bottom screw) to join stronger front and body extruder parts.
2. PINDA support reinforced.
3. Front improved to grip better Mosquito Extruder.

Also I have added the fan shroud used by BondTech (print it using supports to build plate).

2019/10/16:

1. Modified front and body files v2 to support Mosquito Magnum.
2. Improved slightly Sensor_Cover_PC4-M5_MMU2_up and Sensor_Cover_PC10-M5_MMU2_up.

2019/12/30:

Modified front and body files (I have appened the v3 suffix):

1. Two versions (insertion thread or nut)
2. Filament path now is 2.2mm (before was 2mm), so easier filament insertion when using MMU2S.
3. Added an extruder indicator (you need a 7x3mm magnet)
