3D model description

Spoiler: This design is crap ;) I've since replaced it with a hacky horrible looking design, but it does at least work. I hope to polish the new design and post it one day...

A Filament guide for mounting on top of the LCD panel on cheap CTC branded, chinese Prusa i3 style printers (ie. £150 ebay).

I found that filament would snag easily in the pre-drilled hole in the (wooden) frame. Made this to run filament in from above the extruder. Designed to fit snugly on the frame panel, and wedge in behind the LCD's circuit board :)

I printed at about 30% infill (alternating grid), 0.8mm walls, and supports. Pretty sure it would print fine without supports etc, but I wanted it to look clean :)

This thing was made with Tinkercad. Edit it online
