With Passover approaching, my wife (who is a rabbi) challenged me to create a vertical seder plate. I ended up designing a seven piece assembly that holds the traditional seder plate liners. OpenSCAD came to the rescue as the tolerances on the pieces was critical for it to be stable. I have included the source if you want to tweak the design. The arms can be rotated independently in order to fit the items as needed.
Note: Seder plate liners are available in plastic and glass (with lettering) from a number of sources. Just Google "seder plate liners" and you'll be set.
Update 1: I added a larger base that also has thinner spokes.
Update 2: It worked nicely for two seders. One advantage to the Vertical Seder Plate is everyone could see the items versus a regular plate that lays flat on the table.
Update 3 (April 2, 2015): Stratasys selected this design for their Passover e-card.
Update 4 (April 5, 2015): Feature article on 3ders.org:
I used the following settings on my MakerBot Replicator2 to print the pieces. I didn't use a raft and support is not needed.
Infill = 10%
Layer Height = 0.200
Shells = 1
Feedrate = 40
Travel Feed = 55
Temperature = 220
You will need to print one base, one arm_top and five arms in order to make the complete Seder Tree.
Note for OpenSCAD users: There is one file for both the arm and arm_top. Just change the variable "top" depending on what you want to print.
