Version 0.6 was the first to intergrate an adjustable angle thumb including the ability to adjust the distance to the body, but the acrylic proved to be too brittle to secure properly. It was also at this point that another key was added to the thumb cluster and the two vertical 1.5u keys were shortened to 1u to allow the thumb cluster to be moved closer to the body.
Version 0.4 featured a number of asthetic improvements, including countersunk screws and tighter intergration of the thumb cluster. A pivoting base was tested with this iteration as well and Version v0.4.1 added light pipes for RGB indicator lights. At this point a single board was also designed for testing as well on the request of the community.
Version 0.3 tweaked the column heights to better match finger length averages, as well as alter the position of the thumb clusters to bring them into a more comfortable position for those with smaller hands. It also included a more solid support that also allowed the units to sit comfortably over a laptop.
Version 0.2 extended the palm rest and also changed the shape of the thumb drop to improve comfort. Much of the internal cutouts were changed as well to better accommodate the PCBs. However, while the height was comfortable the long legs tended to be unstable.
