About this 3D model

Print either one of them or both and clip them from on top of the lumber. Once printed, put a long piece of 20mm pvc pipe on the printed spool holder. PVC pipe holder on both spool rollers are the same and both A and B can be used together. This will give at about 5-10mm elevation from placing directly on the lumber previously. Print multiple of them same like the lumber holder to ensure it is able to support the weight of the spools.
