Spool Holder

Spool Holder using aluminum tube with a diameter of 18mm.
For the sides of the triangle, I used 150mm long tubes - 4 pieces, 115mm 2 pieces. The length depends on how many coils you wish to use.
To assemble the structure, print 2 pieces with an angle of 45 (one left and one right) and 4 pieces with an angle of 67.5 (two left and two right)
