"Umulius Rectangulum", 3D Printed is my 3D printed interpretation of the origami (paper version) "Umulius Rectangulum" by Thoki Yenn. As was the original, this version requires only one part, 3D printed six times in paired colors, in order to recreate this elegantly simple yet clever Thoki Yenn origami design on your 3D printer.
I've included two sizes of the one part required to assemble "Umulius Rectangulum", 3D Printed in the download, standard and small. A poor quality video of the small assembly process is here:https://www.youtube.com/watch?v=nlL1DDh4PnU.
Depending on your printer, settings, etc., the small version can be printed in an hour or so, the large version requires much longer print time.
Print 6 of either "Rectangle Half Small.stl" (for a smaller version) or "Rectangle Half.stl" (for the original version) in the colors of your choice. I printed two in red, two in green and two in blue for the prototypes as seen in the photo.
Test fit and trim, file, sand, etc. all parts as necessary for a tight fit. Depending on the colors you chose, your printer and your printer settings, more or less trimming, filing and/or sanding may be required. If the components are too loose, add a small dot of thick cyanoacrylate to the side(s) of the male component, allow to dry completely (I use accelerator to speed the process), then try the fit again. Repeat until tight.
