Sphere60 eiffel style
Description
it's just for fun and because i like spheres
Instructions
This is to cut in 3mm thick, for example MDF
cut until you got
24 wheels with 5 slots
40 wheels with 6 slots
60 curved with 2 circles
30 curved with 3 circles
... and some spares
insert 5 "2 circle curved" pieces between two "5 slot's wheels"
once you get 2 of these, join them with the "6 slot wheels" and a "3 circle curved"
continue, you'll get the sphere
And many thanks to thingiverse.com/souriceaux06 for his conversion of the thing to ".dxf" format
thanks to thingiverse.com/amk for the plans of his derivative of 4mm with legs
Ok... english is not my main language... i do my best

I tried to make a version but all cutlines where double so the wood became real crispy. As u can see in the picture of my version.
I made some test parts for this sphere today. Are you sure this is supposed to be for 3mm thick wood? I tried making parts with default sizing, and the holes were much too big to snap together. There was a ~0.5 mm gap where the parts should have fit snugly. When I tried scaling the design down so the parts would snap together, the result was too thin. The parts were so fragile that they broke when I picked them up.
I am using 1/8 inch thick wood, which is about 3.2 mm.
The design is for 3mm but it might work for 2.9, there's a couple of things you can check
- First the exact thickness of your sheets of wood, let's say +-0.1mm.
Don't rely on resellers, i already found an acrylic sheet with 2.8mm on a corner and 3.2 on the opposite. Resellers dont really bother with the difference between 1/8in and 3mm and i guess they eventually re-sand just for the aspect so you might have between 2.7 end 3.3mm. That's a 15% only glue can handle...
Use a caliper or by default stack 10 then divide
then scale or use an stable electric planer
- Caliber the laser, write on a paperblock the speed/power/results. Too munch power cook the wood and makes big cut lines. Find the power that just cut so you'll get the tinner cut line and keep the material properties intact
For example by reducing the thick of an mdf sheet to 1mm and scaling i built a sphere
Amazing structure! congratulations, may you post it in cdr or eps vector?
I post it in .svg and in .odt, i'm sure that .odt works for me. openoffice is a free software that can export to various formats. I will post in others format as soon as i found a way to test them.
But if you export the file to a format working for u, it will be an honour to add it here :)
Looks like you could glue transparent paper in the inside to make a lamp.
Superb work.
Always a question, is it possible to have the file. Dxf?
really beautiful ;)

Could you post the .stl files? I want to print this on my printrbot, and need stl files. I'm not sure if/how to convert them.
i do not have .stl version of this thing
Maybe ask DaveD (hereunder in the thread),
It might be a way to convert from .dxf but i don't know how..
