3D Printed Curta Calculator

Dude. very sweet... I dont think the gmax gets NEARLY enough credit for the quality of its prints. Big huge prints, sure, but if you tune it right it can pump out INCREDIBLE quality like this

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 http://www.thingiverse.com/thing:1659207, but it looks like the 1.5+ may solve some of those issues.

Digital Trends wrote up an article today on the Curta: http://www.digitaltrends.com/cool-tech/ ... alculator/ which also mentions that I printed on a gCreate printer.

I finished up some model changes I needed to make and reviewed all the parts and decided I was ready to release them. They are up on thingiverse at http://www.thingiverse.com/thing:1943171.

I have a BOM and it lists all tools, printed tools, printed parts, and non-printed parts necessary. The printed parts describe basic print settings. However, I still need to write up a build guide -- assembly is non-trivial. What tools are used to make the gMax build guides?
