I've been casting of and on (mostly off) for some years, but my castings were all fairly large and clunky. I'm now able to produce much more delicate models and I'm looking forward to casting them. I would really like some advice on how you would go about sprueing this piece. It would be really helpful for folks to make a copy of this photo and mark "UP" where they think "up" should be when the piece is oriented in the flask and the metal is about to be poured in and place arrows where they would attach the sprues. And if you think the dimensions are too small, I would be glad to know what's the smallest size you think will work (and for which dimension). Hopefully your good advice will save me hours and hours of experimentation! The piece is 50mm long (just under 2 inches). It's 24mm wide at its widest and 2mm thick. along the central stem. The depressions (or cells) in the piece are 0.5mm deep and are on both sides. The "wires" separating the cells are 0.2mm wide and the outer edge wires are 0.3mm wide. The piece below is a draft printing from my 3d printer, it will be printed in the Formlabs wax/resin mixture for casting and the various nubbin artifacts the supports leave will be cleaned up on that version. Thanks in advance for your help!
