Sainsmart

I've had no major issues with cheaper Sainsmart or Overture TPU on Mk2.5. One time loading it wrapped around the toothed idler after a rebuild, but a hard yank unwound it, and then I fixed the tension by reducing it. In PrusaSlicer, Filament/Advanced/Print-Speed-Override, the volumetric setting will be the primary governor of speed.

All have worked very well. Multiple colours of Overture, with some variability in handling same max speed as one another (increase stringing). Used the Prusa Slicer default SainSmart Semiflex settings.

I bought one made by Sainsmart, basically a fire retardant tent. But it’s got lots of pockets and good places to route cables in, plus more than enough space to keep the standard spool holder while sitting on a concrete block.
