Yes, TUSH (The Ultimate Spool Holder) is still a popular and widely used spool holder design for 3D printers. It utilizes bearings to reduce friction and allow smooth feeding of filament. Many users have found it to be a reliable and effective solution.
However, there are also other spool holder designs available that incorporate bearings or other mechanisms to reduce friction. It's worth exploring different options and finding the one that suits your specific needs and printer setup the best.
You can search for alternative designs on websites like Thingiverse or other 3D printing communities. Pay attention to user reviews and feedback to gauge the effectiveness of different spool holders with TPU or other flexible filaments.
Remember to consider factors such as stability, ease of filament loading, and compatibility with your specific printer model when selecting a spool holder design.
