Hollow Sphere Design for 3D Printing

in CAD Design held by dspog
Contest Ended, Winner(s) have been selected.
Description:
Hey there! I need hollow sphere design that will consist of top and bottom parts that will snap into each other to form round sphere. Sphere will be made of plastic and filled with sand (please see specifications below) so snapping must be secure and once snapped together it doesn't need to open again. I am looking for esthetically pleasing design of the sphere itself, specifically the sphere cut out patterns (see my hand drawn images to give you some ideas)
Wants:
1. Sphere has two parts - top and bottom that securely snap into each other to form one round object
2. CUT OUT PATTERN: Sphere needs to have cut-out pattern(s) that must be 1mm wide and any length - sand that will fill this sphere is 1.1mm round so I need to make sure no opening is larger than 1mm so sand stays in. I am really hoping this is where you will spend most of your creative time - I am looking for a pattern that is professional,sporty, high-tech and doesn't remind you of a Christmas tree decorations. :) the more openings the better but it needs to be a combination of function (a lot of openings but strength is not affected so this plastic ball doesn't crash in hands because too many openings too close) and design - awesome looking pattern: ideas - T, H, F, S, L letter pattern shapes, wave pattern, perforation - if you have better ideas then bring them in!
3. Sphere color - pitch black or darker gray color, preferably mate finish
4. Need to add logo - thinking that logo can go on the snapping mechanism area that will stretch on the perimeter of the ball - see my hand drawings - I think the snapping strip is great positioning for the logo
5. OUTER SPHERE DIAMETER MUST BE 29.75mm
6. Sphere wall thickness - 1mm to 1.5mm
7. I need to be able to take your file to 3D printing facility to print prototype, fill with sand and test it so parts must fit/snap well.

@Adam - your first design is great!
@Cad Geek - love the creativity and different kind of snapping mechanism
close call between these two designs right now - I really like both!

hi guys, STL format is what I am familiar with, I think STEP or IGES could also work as far as I can view it with a viewer and is acceptable by 3D printing companies, I know most of them accept STL format
Mon, 24 Apr 2017 15:09:10 +0000
Is Catia v5 acceptable?

it is ok to submit model in IGES or in STEP?

I'm looking to hire someone immediately to provide detailed millwork shop drawings for a living room media unit and walk-in closet (see architect's drawings attached).

Conceptional physics design
This is a abstract design for a physics project about energy conversion using high charge density. The design is called longitudinal plasma vortex energy converter: a counter-rotating outer quartz cylinder with an internal counter-rotating epicyclic gear train with a downward facing rounded point nozzle connected to a low-pressure turbine and located where the sun gear is located. The system also contains a clockwise-rotating inner quartz cylinder with an internal clockwise-rotating epicyclic gear train with a upward facing pointed edge nozzle connected to a low-pressure turbine and located where the sun gear is located. The representation is designed to showcase a closed system in which the plasma is pushed upward by the clockwise-rotating turbine and pointed edge nozzle and then pushed downward on the sides by the counter-rotating turbine and rounded point nozzle of the outer cylinder (motion shown by green arrows). Attached please find a drawing that I want the designer to refine to the best of his/her talent.
