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

Scale Honey Dipper Stick & Stand
Hello there! I'm looking to have a miniature honey dipper stick and stand/holder modeled for the purposes of CNC machining. They'll be handed out with our business cards and help promote our business at events. Thanks!
D&D mini for Noz'dhuk, Archlich of life
I am in need of a miniature for my big evil boss of the D&D campaign I am currently running. This character's form is considered to be a large creature in this game, so the size of the mini needs to be at least 50mm at the base and at least 70mm in height. If the design is taller, I will be able to scale it down. Noz'dhuk is an evil lich necromancer that was emprisoned in an alternate plane many centuries ago. The mini will be for when he gets liberated from his prison, then taking the form closest to what he remembers of himself, which is not much. This form will resemble one of a half decomposed corpse, showing bones and rotting skin. Thin frail arms are attached to big claw-like hands with long fingers. The bottom half of Noz'dhuk is non existent. Being in the form of a ghost or spirit, he levitates above the ground. His clothes are the old ones from when he was an archmage doing his research, thus a wizard robe, but aged, damaged and shredded. I am not decided on if he has a hood on his robes, i leave this to your creative choice. Noz'dhuk has no weapons, he could have a spell book, but this is not mandatory. He could also have four arms, two for attacks and protection (more like beast arms) and the other other for general purpose like interacting with his spellbook, again not mandatory.
Coin Face
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
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
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
