// You will also need 4 x M4 machine screws and nuts.

// ===== Light duty 3-armed spool for 3mm x <=30m coil =====
//
// A light duty 3-armed spool suitable for up to around 30m
// Set
// fdia=2.85
// lightduty=true
+// (or look in filamentspool-lt.scad).
+//
// And print following parts
// Hub
// ArmEnd x 3
// NB that the `light duty' version of this is shorter and
// will only take two `light duty' spools.
//
-// For the above, I used the Cura `High detail' PLA profile because
+// A longer arm for three spools is also available:
+// Set
+// fdia=2.85
+// lightduty=false
+// storarm_spools=3
+// (or look in filamentspool-storarm3.scad).
+//
+// And print one of these, according to taste
+// StorageArmLeft
+// StorageArmRight
+//
+// For all of these, I used the Cura `High detail' PLA profile because
// I wanted it pretty, but the `Standard' profile should do fine.
//
// ===== Spools for 1.75mm filament =====
