YAFSH - Yet Another Filament Spool Holder

pinshape

The end table I'm using as the home base for my Tevo Tarantula has a distinctive underside, elegantly modeled in the last photo, that makes it difficult for most clamp-type holders to get a secure grip. There just isn't enough space to provide a stable hold. Drawing on my years of woodworking experience, I came up with a clip-type clamp that clips over the lower rail to keep the unit firmly in place and holds a small, old mailing tube as a spool holder. This is probably a one-off situation, so I'm including the SketchUp STL file for you to modify as needed for your table. Enable supports everywhere for the clamp to accommodate the mounting hole, but supports touching the build plate are enough for the braces and the uprights. You'll need to print two of each part to have a complete system. Some filing or sanding may be necessary due to printer inaccuracy. The design is meant for a snug fit, but a little glue will greatly improve stability. There's a small amount of wiggle room in my design that's taken up by a thin piece of leather to prevent table marring.
