For fellow trainers who use a Go-tcha.
After a conversation with some friends, who suggested they, like me, don’t really like wearing things on their wrists, I set about engineering a 3D-printable, one piece sheath for the Go-tcha to convert it to a keyring while keeping it safe.
Slide your Go-tcha device (lozenge only, not included), charging points facing down, into the sheath exactly as you would into its charger. Then attach a lobster claw keyring clasp (not included) which will hold the Go-tcha in the sheath. You can now enjoy all the benefits of a Go-tcha, without needing the wristband, but also without losing your precious little catching and spinning gadget! Completely remove the Go-tcha from the sheath when charging.
This product has not gone through any real-word stress testing. I made it to support my own hobby, and hoped it would be useful to others. My friends and I have been using ours without issue since August 2017, but its expected lifespan beyond that is untested and unknown. I do not have the resources for any extensive R&D to test the reliability of the converter, so its use is advised at your own risk of possible loss or damage to your Go-tcha device.
