Design Summary

External

Reflection features a three-piece / three-tone design with a silver base, copper weight, and top color variants. It is an XT FRLTKL (basically a TKL with the F-row removed and a macro column on the side). The board features a large swept cut copper weight that follows the curve of the top piece side profile. The front of the board has a cherry lip of sorts - with the lip being the deepest in the middle and gently flowing into the chamfer on the side edges. There is a gentle cut on the sides and back of the board to give the perimeter some flair. Two engravings are present - one left justified on the back of the board and one on the underside of the board (see Inspiration). The mirrored engraving on the aluminum bottom is half the depth of the one of the copper weight to give the appearance of a “reflection”.

Internal

The board features an internal screw system to keep the weight design as clean as possible. The final screws will be black oxidized and recessed slightly below the plate to be as hidden as possible. The aluminum inner frame has an open bottom so the copper is effectively a through weight giving a nice contrast on both the bottom as well as the inside of the keyboard. The daughterboard is installed upside-down with the cable being colinear with the PCB molex connector eliminating the need to bend the jst cable in a channel. There are small press-fit bumpers placed next to the screw holes to eliminate any chance of case ping. There are no adhesives anywhere on the board so it can be unassembled fully.

Inspiration

This keyboard is largely an homage to my home country of Bangladesh. The green colorway is based on the country flag and the engravings are inspired by Bengali architecture.

The image above is a photo I snapped of the National Martyr’s Monument. Not only does it have a lot of cultural significance representing the events leading up to Bangladesh’s recognition as a sovereign nation, but also has been praised for it’s architectural excellence. It towers over the surrounding garden space and really is a marvel to behold.

There is also a small pool placed in front of the monument - when viewed straight on, this gives a nice reflection of the entire structure. This is why I chose to name it “Reflection” and added an mirrored engraving of Bengali script on the front side of the board which states the name of the board.

Mounting Options

Gasket Plug Mount

The gasket plugs are secured into the plate tabs and the overall assembly is dropped into the bottom case. The top case is then placed over it. This should make for a more flexible typing experience.

Burger O-Ring Top Mount

The plate is fixed to the top chassis using a screw and two small o-ring gasket pieces. This provides a stiffer typing experience overall.
