Next we shall move onto installing the Frame Extensions & Feet Assembly. The frame needs to be extended in order to enclose the printer so printed extensions will be installed. These also increase the height of the printer which in turn allows for more room under the printer to house electronics and keep them cool.

First install the 8 x threaded heat inserts using a soldering iron as described previously on the 4 pieces that make up the rear extensions as shown below

Rear Extensions preparation

Install 20 x threaded heat inserts onto the front extensions as shown below. This image is just for 1 side and 9 of the threaded inserts are visible with the last one being under the front piece making it 10 x threaded heat inserts per side.

Front Extensions preparation

Insert the last 4 threaded heat inserts into the 4 feet extensions.

Feet Extensions

Now that were done with the threaded heat inserts lets get on with building. First lets join the 2 rear extension pieces together using 2 x M3x8 SHCS screws.

Rear Extension Assembly

Repeat for the other side. We can now move onto installing the rear extensions and the four feet. These were specifically designed so that the bottom panel can be removed without the need to remove the feet.

  1. Install 4 x M5 T-Nuts into the outer bottom extrusion of the left and right frame base
  2. Use the M5x45 BHCS screw and sandwich the Rubber Foot, printed foot extension, rear extensions with the bottom frame and screw into the M5 T-Nut
  3. Repeat for the other 3 feet

Rear Extension Installation

Next we move on to the front extension assembly.

  1. Connect the right front extensions a & b together using a M3x12 SHCS screw in the bottom hole (the top hole is purposely left empty as FT EMS frame will attache here later).
  2. Attach the Support arm with 4 x M3x8 SHCS screws
  3. Repeat for the left side and be mindful that the top screw hole is not used at this point

Front Extension Assembly

Now we attach the 2 front extensions to the frame.

  1. If you are using an Ender 3 V2 you will need to TAP M5 screw holes into the extrusion
  2. Install the front extension using 4 x M5x16 BHCS screws
  3. Install an M3x12 SHCS screw into the bottom hole that will join the front and rear extension together

Front Extension Asembly 2

With all that done your printer should now look like this.
