So, buying at least 20 at a time should work out to around $5 a cart. I assume they won't be as pretty as the injection molded shells. I think it's worth it to have the ports exposed though. jlcpcb has a 3d printing service too. They quote about $5 each plus $20 shipping. But that's for SLA resin with sanded finish and it may be possible to combine shipping if the assembled PCBs are included in the order. If we have a design with only the front and back halves it might be viable. The current design can be FDM printed without supports, which is a big "savings" in production logistics for the person printing. However, the embedded logo does complicate things if you are doing the print in multiple colours. It's easy enough to modify the original design, and I'm happy to assist with any changes required, if required. Or, have someone else design it again in Fusion360 - which in the long run might be better anyway. OpenSCAD is a bit esoteric, and the code I wrote to produce the cart shells is rather untelligable, unfortunately. For reference, the design is a snap-fit no-glue-required sort of thing, with 10 parts; the two shells, the logo insert, 6 push-fit pins, and a label insert. My only caveat here is that to do decent FDM printing is a black art and these shells require real attention to detail to print nicely. I would get a small run of samples from any supplier first before proceeding with a bulk order. Quality can vary widely. Quote Link to comment Share on other sites More sharing options...
