2 ring designs for 3D printing/lost wax casting

in 3D Printing Design held by TMDC
Contest Ended, Winner(s) have been selected.
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
aesthetics/apperance, exact measurements etc
  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.

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.

Simple extendable / telescoping mini pole
This will be 3D printed (please refer to images) - 1/8” inch in diameter - one end will screw into a plastic wall that is .25 inch wide (bottom) part - so length of this threaded area should be about .2 inches long (yellow area in image) - the other end will taper into a round dome (top part in image) - the largest length of pole, when fully extended will be .875 inches (7/8”) long - the shortest length when fully compacted, will be .4375 inches (or something close to that) (7/16inches) - the apparatus will be 1/8” long (grey area in image) - the diameter will be slightly wider than general pole diameter - apparatus will have largest diameter - then base pole will have smaller diameter then extension pole will have smaller diameter threaded area should have same diameter as extension pole

I need a cool looking "coin", 52mm diameter, 4-5mm high, but hollow (because it's half the coin really, I have the other half done), with a 1mm edge all around, hollow cavity 50mm inside the edge and 2 mm high, leaving 2mm for the face which can be embossed like a real coin. It needs to be printable on a hobby printer with .4mm nozzle
