TPU cover for nut runner

this is the tpu cover for the centre spinner in my nut runner model on my page printed in 95a tpu but others could experiment wether a softer tpu would be beneficial UPDATE:the tpu cover does help with slipping when using the nut spinner but after some experimenting and further use ive found that double sided tape and rubber grip tape are a better choice as they offer more grip and less slippage the only downside so far is eventually they need replacing as they will wear down. if theres anything youve found that works well for you please drop a comment and let me know. please consider rating my model and checking out my page
