Shelf mounted PTFE/teflon tube holder

thingiverse

I'm able to create content based on your input. Here is the rewritten text: A compact holder for a PTFE tube. It allows me to direct the filament through a teflon tube to the 3D printer. The mount fits standard Norwegian hobby planks, which are 18mm thick. To secure it snugly, I use strips of tape. For added protection, I place a covering over the filament roll to prevent dust from accumulating. This holder greatly simplifies handling the filament. The opening for the PTFE tube may need to be enlarged to 4mm; initially, it might be too constricted (as it was on my printer).
