I looked at LOTS of filament guides but decided to design one for my specific geometry.

The slot guides PTFE tubes from two Sunlu dryers down into my ¾" thick plywood enclosure through the top panel. I will have two dryers sitting side-by-side and the slot allows the PTFE tubes to wander freely with the XZ axis movements, even with the dryers off-center.

I'm going to add a brush style seal to the bottom edge for keeping heat/odors inside the enclosure to be dealt with by the filter and exhaust systems.

The 3mf file is set up for two colors with a 5-layer blue stripe in a black body to match my control panel.
