alternatively, you could remove one wall off the groove and fill it with a poly carbonate ring to stop snagging ---

A plastic that can be machined to the correct thread size might work. I see nylon threaded components at that size, but I have no idea if that material would work as a finger-spinning surface. Assuming that you want to minimize weight, POM and PC are significantly lighter than AL, but the trade-off at the amount of material here vs. strength and manufacturing difficulties might not be worth it. ---

> [@AtomicChessGuy](#): > > Should have a space for a Allen Wrench/Hex Key now. maybe a slot instead of hex - less chance of stripping it, and easier to manufacture. plus, there’s no risk of the screwdriver slipping out of the slot when it’s inside of the yoyo like this, so pretty much no downside, right? ---

If these are metal caps I would consider adding like a small step or something on the cup so you can use a rubber gasket to cushion the metal on metal contact. Otherwise you might want them to not be fully flush. ---

Not enough room for a slot? or for the screwdriver? should be reasonable for both - you can buy stock m4 grub screws that are slotted; and there’s lots of smaller types of screwdrivers that can fit into an axle hole just fine. ---
