You get to make a 3d printed chair.
Here’s the twist: it will require assembly using a specific fastener known as a M3 screw. This will be printed disassembled and held together with fasteners.
BEFORE you start designing in CAD:
1. review chair styles
2. draw a scaled version of your chair design and mark where the fasteners will be placed.
Design requirements:
- Your chair design will be printed FLAT and will be assembled with M3 fasteners and nuts.
- Your chair should have at least one design element like and image, decorative designed hole, or texture.
- Designed for flat packing which means:
-no single piece should require supports
-should be able to lay flat on the build plane 
Chair measurements:
Fastener measurements: these are really important. Without proper sizing your chair won’t assemble well.
Fastener hole: diameter of 3.3mm allows for the fastener to slide into hole.
Socket for the nut: thickness is 2.1mm for a press fit.
What do you turn in? Complete step 1 and step 2.
1. Canvas: a screenshot from Tinkercad of your finished design. How to take a screenshot in Windows.
2. For printing: upload the STL file of your design to this Google Form.
Here’s how to convert files to STL:
-in Tinkercad click the EXPORT button in the top right hand corner. Choose STL as the file format. Pay attention to where the file downloads on your computer. -make sure that the file has your last name (like milsteadcompleteshape.svg). No name=no 3d print.
