1 x 2 rino holder
myminifactory
I printed with a brim and 25% infill, adding supports for areas not touching the bed. I've dubbed it the Rino Holder because my kid thinks the end of the spool holder resembles a rino horn. To sit over the 3D printing nerds' brackets, it has a notch and clips on either side. With these modifications, it's smaller than a standard 1KG spool from inside to inside, making it ideal for fitting in front of a single spool or alongside two spools. The nose of the spool holder isn't massive, but I've had no issues with my own creation so far. Sorry about the subpar pic taking.
