Review on ➰ OVERTURE TPU High Speed Filament 1.75mm Flexible TPU Roll - Top-Quality 3D Printer Consumables, 1kg Spool (2.2lbs), Dimensional Accuracy +/- 0.05mm - Perfect for Most FDM Printers - Clear, 1 Pack by Nicholas Lim

It took me several tries to undo all the creases. Printing with it from a pocket is easy. Just loosen the idlers a bit so they don't bite into this thread as it is very soft. I printed my phone case with a layer height of 0.15 and it came out great. For subsequent prints, I put the spool in the Sunlo dryer, and every time the filament got too soft in the middle of a print, the filament got hot. Instead of going straight out of the dryer, I let it cool down a bit, put the spool on my printer's spool holder, and there was no problem after that. The prints are excellent. My first print had very little thread, but later prints had slightly more thread. However, it's not that bad. The bridge is a bit of a problem when the phone buttons go. It's hard to get a perfect result, but overall I like the result and I highly recommend this black TPU thread.
