ReelThin1500

I found the reel holder supplied with the printer is a bit draggy and not best, especially for TPU. I obtained some 4mm tungsten carbide amalgum rod. Steel would do or stainless. Use this as an axle and print these items and the reel rolls with little resistance, so no starvation on TPU builds, etc.

Example product. Not exactly the one I bought, but similar things can be found.
