The file 'Canvas Holder For Welland Easel 3D Printer Model' is (stl) file type, size is 18.9KB.
I made this to stop the canvas from slipping out of the canvas holder on the Winsor and Newton Welland Easel, though it could be used for any easel. It just requires 2 small screwws to hold it in pkace. It measures 13 cm x 1 cm.
