Generally speaking I agree with more is less when it comes to engraving. There are exceptions though. Some of the older 888s had fantastic engraving. ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/3X/4/0/40c44f201b93f21b2107e12bee91a37ad26346ae.jpeg) ---

If thatā€™s the grail, do you have more detailed designs? I was thinking about asking a friend of mine to build one. Solid works designs would probably be better though. ---

The design is for 7075 Aluminum. Be forewarned - while this might superficially resemble the grail, itā€™s never been prototyped, and I havenā€™t actually thrown a grail. It probably wonā€™t play like one. You should also probably fix up the silicone recess to match whatever pads/etc you have. Iā€™m still sort of baffled about what dimensions they should have to be compatible with the most common pads. ---

hereā€™s a prototype iā€™ve been working on, im hilariously new to cad though so i cant actually say how the design will play, if itā€™s machinable, or even tell you what the weight is as i have no idea how to add a bearing, axle, and response into the design. also, any ideas on what to do about the fact that you have to buy 5 if you want to get a throw prototyped? i only really want 1-2, but i cant imagine that anyone will want to buy some companyless amateurs first prototypes, so im really at a loss as to how iā€™m supposed to tackle this 500+$ pricetag that really isnā€™t necessary. ![concept_1_2018-Sep-16_04-46-48AM-000_CustomizedView25017069532](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/8/5/8/8586da9c47a11fd9528911cb250637b237201b07.jpeg) ![concept_1_2018-Sep-16_04-55-09AM-000_CustomizedView27698650067](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/4/8/9/489d7922a90455b2607f271eaff25b4364a99a06.jpeg) ![concept_1_2018-Sep-16_05-07-16AM-000_CustomizedView1477354480](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/f/1/2/f12a61c7aefb51e3a3bd4de7e10bc2f45a5b6b84.jpeg) ![concept_1_2018-Sep-16_05-22-48AM-000_CustomizedView9861501228](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/5/f/6/5f6df9ef2cf3a0fa4e8d193fd385564d4f8f96c6.jpeg) ![concept_1_2018-Sep-16_05-27-24AM-000_CustomizedView3806683159](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/3/3/b/33b5785e44e63d9343be711dae5ff49bc4702cac.jpeg) ![concept_1_2018-Sep-16_05-49-48AM-000_CustomizedView33681882117](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/1/4/7/1475ddbde886bf1f533036d7964f6788bb122d57.jpeg) ---

You should also definitely have your CAD software calculate the weight of a half. You can generally add about 3 grams + the two halves to get the assembled weight. The reason for the high cost for small runs is that thereā€™s a lot of setup time for the machinist & the lathe. The more you make at once the cheaper they will be, depending on how long it takes to machine each half. As for your design - you should add a fillet to the edge of the rim to keep it from being so sharp. Itā€™s also not very likely for your first design to turn out to be the one you want to make - Iā€™ve made dozens and dozens before settling on one that Iā€™m interested in producing (in a small run). Each one Iā€™ve drawn has taught me how to work with another type of feature. ---

kk, then the specs (from what i can discern) are: weight: 62.892 width: 45.022 OD: 53.898 again, weight is without axle, bearing or response. ---

also, that outer edge _does_ have a fillet, but i guess it should be larger? although i thought that it didnā€™t really matter how large the fillet was because itā€™s still rounding something out that is otherwise infinitely sharp. but, that was just a theory i had, so tell me if that line of reasoning is incorrect. ---

Thatā€™s pretty reasonable, then. Just take another pass over those sharp parts, and measure the wall thickness everywhere to make sure itā€™s \> 1.5mm at minimum (if using 6061). Also, when you do your renders, use a softer lighting environment. It helps a lot, even if just doing it for fun! ---

The fillet might be too small. For an acute angle like that you probably want to try a 1mm radius fillet on that corner.

yup, minimum wall is ~1.65mm. and i did some renders with the default soft lightning settings, but it was too dark to illustrate those 2 inner spikes, so i had to crank the brightness. what kind of settings do you have for your renders? they all look really good!
