Ouch! Keychain Fidget EXTREME! so the Ouch Keychain Fidget extreme, Firstly a warning that these are probably not suitable for small children as they are pretty sharp. If your not familiar with these the idea is that they are a safe form of self harm, mainly aimed at autistic, ADHD and those with Anxiety. With that out the way there is some changes, i have made them shorter in size at around 70cm tall, we have new patterns and ive introduced the thumb sphere. The thumb sphere mainly has come because i personally find spherical indents super nice to feel, This does require a small support to get the indent to be nice and smooth, i would also just add a little heat to the inside and run you finger around just to smoothie out even further. Ive printed in a rainbow, its called summer revive but unfortunately hasn't got the brand on the spool. Other wise its 0.2 layer, 15% infill.
