I am using the JSAUX Slim Travel Case for Lenovo Legion Go and it fits the claw 8 quite well and is hard yet slimmer than other fat/full size cases 👍 https://www.amazon.com/dp/B0GD7BDLH4
Then I think you have already had the answer. The JSAUX Slim case, which they sent you a link to Link to product or the 3d Hard case that a member sells on Etsy are PERFECT for your case. Surely the rigid 3D one is more usable since, if necessary, you can detach the part that contains cables and charger or take it with you on a trip but the price is double. Anyway... REMEMBER: you have to protect a device that costs 1000 euros/dollars so choose a PROTECTIVE product (for this reason I am not very much in favor of slim cases)
The slim JSAUX case still fits these grips, albeit a little tight but nothing that’s actually pressing on the sticks or damaging anything: https://a.co/d/02lzLGr7
