Overengineered Saucer Rack

thingiverse

##Please Read## To create a rack you need to print: - 1 left rack - 1 right rack - 2 cross beams All 4 pieces should be able to fit on an Ender 3 or a larger printer if the two side pieces are interlaced. **Make sure to print the chamfered faces face down, otherwise the dovetail joints and snap fits may not work properly.** Also note that the left and right sides are not interchangeable, and if you assemble them the wrong way, daisy-chaining may not work. [Check out the assembly video here](https://www.youtube.com/watch?v=t_BGSsXJ5V0) The rest of this readme is not required to make this saucer rack. Enjoy! ### Plate Rack### This is a plate/saucer rack that I designed based on bracco23's cupboard plate rack. It has some modified features. - Added fillets for strength - Shortened crossbeams from 10cm to 8 cm to accommodate smaller saucers. (send me an email/leave a comment if you would like a larger one too) - Removed screw holes on joints so that there are no overhangs in the print - Added angled dovetails instead of regular finger joints so that screws are not required to hold the parts together - Used snap-fits to facilitate assembly - M4 countersunk holes added to cross beams if you want to secure the rack to the floor/shelf with screws ##Design Choices## - All mating features were designed with a 0.1 mm tolerance. - Snap-fits were used to prevent the rack from coming apart. These snap-fits can be undone several times if the fit or orientation is incorrect - Dovetails replaced finger joints so that the racks could not be pulled apart in the front/back direction. - Dovetails have compound angles so that the racks cannot be pulled apart in the sideways direction. - Chamfers were used in some key areas to ensure that [Elephants Foot effect](https://www.youtube.com/watch?v=zlgR3rHg4p8) does not interfere with critical assembly features. - Relief slots 2mm width were used. They extend 5mm into the main body of the crossbeams. This is to prevent the snaps from breaking. Feel free to leave a comment or send me a message. I will incorporate feedback on my models in the next iterations ##Next Steps## - Because of the symmetry of the cross-beam, it is currently possible to install the left and right sides of the part on the wrong sides of the cross-beam. If I modify this design, I will make sure it is not possible to assemble it incorrectly like this
