2 ring designs for 3D printing/lost wax casting

Contest Ended, Winner(s) have been selected.
Description:
looking to get the first 2 rings of my design recreated in CAD so i can get them 3D printed to be used in lost wax casting, the final products will be made of brass.
RING 1: rectangle face with approx 28mm X 24mm with bart simpson engraving, in 2 sizes US10 (dia 19.84mm) and US8 (dia 18.19mm)
RING 2: square face approx 14mm X 14mm with spider web engraving, in US6 (dia 16.51mm) and US8 (dia 18.99mm)
each ring will need to have a sprue for casting, please see pictures provided.
please see design sketches for rough idea of how they should look.
i have included photos of other rings with a similar finish/engraving
looking for someone that has some experience with 3D printing for casting but not essential, i also have more designs really to go for use on the same rings so would like to do more after these. this is the first time i have posted on anything like this so any feedback would be greatly appreciated.
any software that can generate STL/STEP/IGES files should be ok
price not set in stone either
Wants:
aesthetics/apperance, exact measurements etc
Software:
  1. SolidWorks
  2. Autodesk Inventor

#3 Ring 1 Design US10 Size by sldraftingdesign
Here is my initial design for the US10 size. I included a ridge around the edging to mimic Bart Simpsons hair and I have included the overall design I believe you are looking for. Please let me know how this design fairs and I can make any changes you request. If you like the design, I can make the other size

#12 Ring 1 - US 8 by handsketcher
If possible please try to make a sample out of this (I have attached step file for that). Because casting defects on the artwork might be the problem in this task. So I designed it in a way that it will not make significant damage to the artwork. Before moving to all other rings it would be good to know.
Please review the attachments and let me know your feedback.
Thanks,

Trim Scissors Necklace Pendant - Tritium Vials - Shapeways 3D Print
Hey Cad Crowd! Got another project for the personal jewelry collection I'd like done. Trim Scissors as a necklace pendant. Trim Scissors? Yes, Trim Scissors. I work in the Colorado Cannabis industry and a sign of good times to come is trim scissors. Nothing more satisfying than sitting down at a table and manicuring your hard work after busting backside for several months. So I'd like to make a scale version that will work as a necklace pendant with some Tritium vials in the handle portion for additional cool factor.
CAD Design for Four Simple 3D Mathematical Functions
Hi there, I am planning to do some 3D project that needs to be printed by a 3D printer. In order to do so, I need to first have a CAD file of my 3D objects/figures, and I have no clue how to do the CAD design by myself. So, this is why I am reaching out to you. Speaking of the project that I have in mind and now actually ready on papers, I would say that I need someone who is able to design the CAD files of four 3-dimentional mathematical functions (very simple 3D planes/surfaces which are supposed to be placed in a cubic framework which is 10*10*10cm^3 in size) with some certain specifications (colors, thicknesses, etc.) that I have already decided about and everything in form of a 2D version is on papers right now. To be honest, although my project is pretty straightforward, I want it to be done very carefully and professionally. I just need someone who is expert enough and patient enough to make a nice professional CAD file for me. I have roughly one week to get this project done, and everything with that should be done by Friday 23rd. However, the sooner, the better! I will await your replies. Best, Ali
