Yarn Spooler Final Frame
Frame Remix by Funkton was not good enough for me as it has to be printed with wrong filament direction. After it lost 2 of it's "ears" in a month I remade the base one by jonmessenger and now it still prints with correct layer orientation without any supports but can be firmly screwed down to some planks or straight to the table.
Can be assembled with either M4x12 bolts, or M3x12 with hot melt inserts.
Screw-down holes are for M4 countersunk screws.
