K1 Max lid extension with sliding lid & vent covers.

• Increase clearance so the bowden tube does not rub on lid.

• Included are 30mm / 40mm / 50mm / 60mm riser versions (pictured are the 50mm riser).

• The edges form tract to allow lid to slide open & close.

• Assemble in alternate orientations to allow lid to slide to: rear, left, right, or forward.

• Four vents with sliding covers.

• Fits around top lip of printer to securely hold extension in place.

• All parts are 3D printed, no bolts or drilling needed.

for 0.40mm nozzle I suggest
2+ walls
0.20 - 0.30 layer height
0.40 wall width

Align so the outside vent edge lays flat on the build plate.

Supports are needed, set support placement to "Touching Build Plate".

The front and rear frame files each have two edges (left & right). For the extension height of your choosing print FRONT, REAR and 4 copies of the vent cover.

To Assemble:
1) Remove support material.

2) Slide vent covers into tracks for the four edges with vent holes.

3) Carefully remove lid from printer and set on a safe surface.

4) Install both rear frame edges around the lip on top of the printer (see pictures).

5) Keep in mind that the frame edges have a fairly snug fit, slide each edge firmly into its appropriate corner as you go to make next steps easier.

6) Now slide the lid into the track formed by the rear frame edges, sliding from the front. (Alternately lid can be inserted after all frame parts are installed but the handle will need to be temporarily removed from the lid). The inside part of handle makes contact with the rear frame edge by design to reduce risk of lid being opened to far during use.

7) Next install the front edges. The frame edges fit together snug so make sure to slide them fully into place. Easiest to rotate the edges into place as indicated from the pictures. The last edge to install will require a modest to firm amount of force.

Optional: The frame edges are held in place by friction and have no connections between them, there should be no movement, however if you desire you can print extra vent covers and use them as sliding pins between the edges (the tracks of the edges align with each other).

Hope you enjoy the extensions. I find them a necessary alteration to the K1-Max.
