Hello! Welcome to the Geodesic Dome home page for all your geodesic dome home needs. I only make one geodesic dome, but hopefully it is good enough for your needs.
For proper assembly, please print:
The above quantities are correct if you avoid printing my keystone print, which I recommend you skip.
For proper EMT lengths, grab:
-(30) pieces of 3/4" EMT conduit (mine are 42", yours can be any length)
-(35) pieces of 3/4" EMT conduit (mine are 47.375", yours can be original length+5.375")
Each of these pieces needs to be uniform in length, and have two drill holes on the same side, each 0.5" from the end. To ensure proper cutting and drilling, I recommend printing my EMT cutting jigs:
-EMT Jig 1
-EMT Jig 2
-EMT Lever (2)
Use any nail or screw you have lying around to create the axle for the lever. The conduit used to hold the two jigs together should be 0.25" shorter than your required length. To cut the pipe I use a sawzall and some cutting oil.
For screws, you will need like 130 screws, I use Mcmaster Carr P/N 92364A196 Pan Head Screws, but I am sure you can get away with any #8 5/8" screws.
During assembly, follow the instructions on the attached PDF. Make sure any piece with a indented circle on the prong gets a "small" EMT conduit instead of the (large) EMT conduit. It should be easy but is probably not that easy but let me know how it goes.
DISCLAIMER it's made out of plastic pieces. These have flex in them and allow the EMT conduit to flex, allowing them to bend and snap if you put weight on the middle of the EMT conduit. ALSO, don't use PLA like I did.
