It’s an extremely snug fit, but that’s no bad thing. My vernier calipers have gone missing (along with my 25m 4-gang extension reel) at just the wrong time, and measuring curvy things with a straight-edged rule is not the best.
I’ve had my 3D printer, a Monoprice Mini, for a few years but I’ve yet to print with TPU. I bought a small roll of TPU a couple of months ago but I need to print some mods for the printer first to use TPU.
And the primary reason for the TPU purchase is to print a mount for a 360Go.
I used the PLA settings in prusa slicer but adjusted the temperature to suit TPU and saved it as a custom profile worked a treat. Don’t believe everything it says on the internet… it says an ender 3 cant print tpu because its a bowden extruder and you need a direct drive for tpu BULLSHIT!
The main thing with TPU is keep it super dry! I print mine straight out of a 50 degree dry box. And buy decent TPU I use Esun TPU its a bit more expensive but prints so much better than the cheaper stuff
