Prusa Mini Extruder / X Carriage for E3D V6 Hotend V3

Prusa Mini Extruder Section - Using BondTech BMG 3:1 Dual Drive Gear System.

I created this using the original Prusa Mini Files and the model of the BondTech BMG by MarcoZ76. In my build of the Prusa "Midi" (my slightly larger Mini build at 220x220) - one of the hard to find parts that Prusa made is the Extruder Gears. The Titan and BMG stuff is the same ratio, but different physical size. I also didn't like that they went away from the proven dual-drive BondTech gear system that works so well in the i3 series - so here is my solution to upgrade your Prusa Mini to a Bondtech BMG!

Not only is it easier to find these gears - Original ones or Clones, but you are adding the undoubtedly better filament grip of the proven dual gear system, while keeping the torque and resolution of the 3:1 gearing!

This was created and released here prior to Bondtech's own Prusa Mini BMG as well as any other sold at retail. My design still has provisions not seen on others such as filament runout switch mount and handling the wire bundle in a way less prone to blocking the X carriage and bending the wire bundle sharply. Although it is not the same part as Bondtech sells at retail, it is still based on their gearset design. This design should only be used for private use, and not commercial purposes - Bondtech SE sells a similar product at retail.

UPDATE 2/23/20 - updated the main base to provide clearance for Z-Axis, added Revision Marks to main body pieces and cleaned up some excess material. Also, added Zip-Tie points for the wire bundle going to the Hot-End, as well as a pinch bolt / mounting bolt for a Filament sensor (instead of just letting it dangle off the end of the Bowden tubing)

UPDATE 6/8/20 - Adjusted Zip Tie Holes for easier fitment, and added more material at mounting base to provide clearance at full Height Z Axis. Verified holes aligned with newer R4 Z axis parts (they still do - nothing had actually changed there in relation to mounting the extruder, but I received a comment that it was a concern so I checked!)

UPDATE 10/18/20 - Added Sensor Bracket back into STL file - was inadvertantly removed on previous update! Uses the standard "Microswitch" type that are common on Ender type printers with 20mm spacing

This is still a work in progress - I will post any updates as I find them

Reworking my Wanhao D9 to get rid of the atrocious X Axis Bar and Gantry system. These parts allow use of inexpensive MGN12H Linear Rair on the X axis, and along with the Linear conversion parts available for the Prusa i3 Extruder, allow mounting of a much better Eco-System of hot ends and a more accurate X Axis system. Credit for the Linear carriage parts goes to Kalleknall - whom I remixed these parts from.

Prusa Mini Reinforcement Strap - Normally made from Aluminum on Factory Printer - This can be used as a template to create one from Metal, or simply printed at 100% infill and used as-is!

UPDATE 02/22/2020: Added new STL to file with Vertical Ribs to sides and closer tolerances to vetical guide rods / Z Axis Leadscrew. The Center Hole is sized to fit a 608ZZ bearing to support the Z Axis Leadscrew if desired. The Vertical Ribs add much stiffness to this plate in case you decide to use it as a functional part of your build, as opposed to making / buying an aluminum one (they are starting to show up on AliExpress this month)

My Prusa Mini build started as something to do with some extra parts I had lying around from an i3 clone, while waiting for my actual Prusa Mini Order to ship in the spring.

I had some typical 220x220 heat-beds and build surfaces, lots of 300 and 320mm guide rods, and NEMA 17 steppers. Had a few E3D V6 clones, so I ordered up a SKR Mini E3 board and 3.5 Touchscreen display, and started remixing parts to put something together. Had to order the 10mm guide rods and bearings, but it's come together nicely. As of 02/22/2020, I just need to finish adjusting the firmware file for this configuration, and to display the touchscreen in Portrait Mode to fit this form factor.

What i've ended up with is 220mm cube build volume printer (similar to original i3 or Ender 3, but in a much smaller frame. We will see how well it works, but a bowden fed V6 and TMC2209 steppers can't be too bad!

Replacement cover for Kingroon KP3 Printer - fits the BTT / BIQU TFT35 V3.0 Touchscreen. 

I created this to upgrade the Printer Control Board (I used the silent SKR Mini E3 with TMC2209's) and allow space for accessories like my EZABL Pro's Power Board from TH3D.

This cover leaves as much space as possible without interfering with the Y Axis Gantry or Heatbed - but please note that is does NOT have the threaded hole from the stock cover for use as a Z Axis Endstop adjustment (I swapped over to a Bed Leveling Sensor - hence no need for the Endstop screw).

Building a Prusa Mini from Scratch? Use this part to mount an MKS TFT35 V3 Touchscreen in the stock location, for slightly larger screen and more options like Filament Runout, Power Interupt, and Wifi! I am pairing this with an SKR Mini E3 board and building a Mini (until my Factory Backorder Ships!) This part is a remix of the Stock Prusa Part and "Bigtreetech BIQU TFT35 v3 case + 2020 holder + Universal Mount" by gsxr2001 on Thingiverse: https://www.thingiverse.com/thing:3994896

Prusa Mini - MKS TFT35 V3 Case / Mount

Parts to convert the Kingroon KP3 X Axis from 20x20 V Slot Rail over to a Precision Linear Rail system (Like the Y Axis). These parts allow you to remove the V Slot Rail entirely, and replace it with an inexpensive (under $20USD) 250mm long MGN12H Linear Rail kit (such as the one here: 

https://www.amazon.com/gp/product/B07GBNTJW3/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

In addition to these parts, you will need a 4x M4x15 screws, and ideally an M4 Tap to put some threads in the rail's pre-drilled holes. If you don't have the ability to do this - some M3x20 screwes with Locking Nuts will also work. Transfer the X Axis Belt Pulley over to this part, and flip the X Axis End Stop switch to the inside of the cover to which it mounts.

The X Carriage can be mounted to the MGN12H Carrier by drilling a few holes in the stock metal part, or you can print one of the many designs for the CR10 Linear Rail conversions found here in Thingiverse.
