Update 3/9/2017 -- I have assembled a second Curta and taken loads of pictures along the way. I can now either work on a build manual utilizing the photos I took or a series of build videos. There are a LOT of photos and a lot of steps involved. What would you prefer (google form poll)?
Update 01/18/2017 -- I have updated the transmission gear and lockout parts to be printable using a 0.4mm nozzle instead of a 0.25mm nozzle. Thanks to the feedback from MikeHenry. I also updated a repaired Lower Housing.stl due to non-manifold edges.
Update 01/06/2017 -- I found that the tens bell also had non-manifold edges causing problems when slicing. A repaired copy has been uploaded.
Update 12/30/2016 -- I found that the main axle and step drum had non-manifold edges that may cause problems when slicing (Simplify3D skips a few layers in the next to last row of teeth). I uploaded a repaired copy.
Update 12/17/2016 -- I found a part I had missed uploading a file for. It's the securing spring for the zero positioning plate. I have now added the file and added it to the BOM.
Update 12/12/2016 -- I just added layer height, infill, orientation, and support notes to the printed files in the BOM. First step in getting actual build instructions.
The Amazing Curta Calculator is now 3D Printable!
After a lot of effort, I have collected everything needed to 3D Print your own Curta Calculator! This includes all 3D print files and a BOM listing tools and non-printed parts necessary for full assembly.
Note that assembly is incredibly difficult requiring knowledge of the calculator and where parts go, in what order to assemble, and how to properly calibrate the device. I do not yet have instructions completed for assembly, but they will be coming as an instructable. That will be done sometime in 2017.
