Thanks for the compliments. No need to pay for the design files, Kyle, I will be releasing them to the public. However I have gone through multiple revisions and there are some tools that need to be created which I need to update / improve. I will need to go through it all to collect and organize it before I release it. With as many details as I focused on for this, I just can't go half-way with the source release.
There are ~240 printed parts and around ~100 non-printed (springs, ball bearings, and screws). Many of the printed parts require significant amounts of support (I highly recommend Simplify3D for this job) and a seriously tuned printer. I used an e3d cyclops loaded with a 0.25mm nozzle for many of the smaller parts and a 0.4mm nozzle for the larger parts. I also solved some rigidity issues on the x-axis by modifying it to route the belt through the v-slot extrusion with the pulley and motor aligned with the extrusion. The files for the modification are at

Digital Trends wrote up an article today on the Curta:
