Print Ready

Print Ready is a service inside ChatGPT that gives your AI tools to design 3D models, see and iterate on them autonomously, refine them with you, and finally return COMPLETE and print-ready STL files.

Replacement slats that match the existing deck tiles.

Separate white organizers with blue rims, filled with cable ties and tape rolls.

How to use it

Print Ready encourages you to TAKE PHOTOS of anything relevant to the part you're trying to make, such as the area it should fit into or a broken part that you have.
Print Ready can estimate measurements of your part, but it's best to measure and tell Print Ready the most important dimensions of your part.
Print Ready assumes you have a printer of a typical build volume, but doesn't know what you're printing in. For more control, tell Print Ready what printer you're using and what plastic you'll be printing with.

We will be designing a shelf to hold my baby’s milk bottle and a book that will mount on top of one side of her toddler floor bed frame. I’ve attached a picture of that. The dimensions that you should be aware of are that the frame at the top is 19 mm thick, and the bars below them that you’ll probably use to clip or latch onto or something are 16 mm and 34 mm long. Between them is a distance of a little over 65 mm. The top bar, the one that is 19 mm thick, is 46 mm deep.

The shelf should sit centered on top of this bar and should be easy to attach such that it is held tight to the bar with no extra equipment if possible. I want it to be about 8 inches by 6 inches along the frame, about 4mm deep with a slight 2mm lip and four 5mm rounded corners.

Design me small bracket I can mount the male end of an HDMI transponder to.  It should have a little maybe 1x1 inch surface area for mounting tape to be applied to, and the hdmi transponder should plug down into it from the top, to hold it while not being used.  The transponder is 12mm thick and the hdmi port is centered on one of the small faces on the end.  I want about 1mm of clearance between where it's being held and the wall behind it.

Today, you will be designing a plug for the handles of this toy box that are dangerous if a child were to get their finger through and then open or close the lid. I actually have already jammed my finger in there myself, so this is a challenging project.
You're going to have to use image tools in order to infer the correct ovular shape from this picture I'm sending you. The two dimensions you're going to need are:

* The entire oval is 94.0 mm long.
* The total thickness of the board is 17.1 mm.

The design of this thing is going to be a plug where there is some decent tolerance, maybe a couple mm on every side of the oval. Trace that shape, and then this is going to be a through plug from both sides, where there is a very thin layer of plastic on one side that just covers up the hole like a flange. Give it probably 4 mm around the edge so it can't go through in any direction on the inside. That piece must be only 1.5 mm or so thick, and it must be chamfered off at the edge so that the toy box lid can smoothly glide over it.
On the other side, you have a little bit more tolerance. Maybe go to 3 mm or so of thickness, but the exact same flange size and shape. There's going to be a singular bolt hole right in the middle so that I can put a bolt and nut through. Put the nut inset on the inside, and the bolt goes through the outside, so that I can attach these two plugs together in a way that the kids cannot remove without a screwdriver.
The inside absolutely cannot extend past that 1.5 mm tolerance I gave you so that the lid can slide by it. The bolt nut inset needs to be entirely within the shape of the plug, meaning there's probably going to be a slightly different shape of the actual plug itself on the inside versus the outside (even though the flanges that hold them to each side are going to be identical).
The bolts I'd like to use are about 14 mm in threaded length and have a 6 mm or so outer diameter. Do whatever research you need to use appropriate tolerances for this, but it should be a pretty nice fit with not a lot of slop.
