Spool holder bracket

Bracket to wall screw to hold a bar supporting spools of filament, engineered with ample clearance for easy installation and to accommodate the 30mm hub and 70mm arms of the http://www.thingiverse.com/thing:612878 design. This deliberate clearance allows effortless fitting even in close spaces. Instructions for use are straightforward: I fabricated this bracket with a wall thickness of 1mm and a fill density of 40% to guarantee its durability. A specific choice of PLA material was made, given the recurring difficulties encountered while printing large ABS parts. For thorough testing, I affixed a 3KG bag of potatoes to a single bracket, which exhibited no signs of weakness or deformation. A prototype version with a visible crack showed remarkable strength despite this initial flaw. The rod used is a salvaged aluminium tube from an old vertical antenna, demonstrating both its lightweight properties and resilience. Important precautions should be taken when screwing the bracket into place: ensure straight drives and avoid over-sized screws to prevent layer delamination.
