About this 3D model

I have a heavy spool of TPU, so I don`t want to put it on top, thats why I made this guide. It`s super tiny in case extruder head will go up and meet it. You can add a drop of oil. P.S. not usable with high prints. P.P.S. better combine with bearing spool holder, like this - https://makerworld.com/en/models/112628#profileId-152615 + table mount.
