NANIWA sharpening stone cases

Dimensions were based on caliper measurements before discovering NANIWA's product page with slightly different numbers. My stones were for example taller than the officially listed sizes, so I decided against editing the cases to match. Cases printed with PETG, and the standoffs with TPU. Each stone use 8 pcs 5x3mm TPU buttons, and each case use 8 pcs 5x5 mm magnets. No support needed.
