These speakers are a customized version of http://www.thingiverse.com/thing:451253, created using the customizer tool at http://www.thingiverse.com/apps/customizer/run?thing_id=451253. All credit goes to Rich Olson who designed this - http://www.nothinglabs.com/speakergen-parametric-3d-printed-speaker-enclosures/\nIt was printed on the Monoprice Select Mini using Hatchbox Wood filament at 215°C extruder/55°C bed temperature. A raft was used but no supports were required, as the mini handled printing the roof of the box without them. This suggests that results may vary when trying to print the roof without supports.\nCustom drivers and terminals were ordered from parts-express.\nDrivers - https://www.parts-express.com/dayton-audio-rs75-4-3-reference-full-range-driver-4-ohm--295-380\nTerminal - https://www.parts-express.com/round-speaker-terminal-cup-2-15-16-gold-banana-binding-post--260-283\nA Lepai 2020+ mini amp with a 12V 3A power supply was used - https://www.amazon.com/Lepai-LP-2020A-Tripath-Amplifier-included/dp/B009IJTMOE/\nThe speakers exceeded expectations, producing surprisingly good sound quality. A finish of two coats of minwax stain and two coats of polyurethane was applied to complete the project.\n\n \n \n Instructions for Use Using the following settings: speakerHoleDiameter = 57 manualBoxVolume = .58 driverFS = 73 speakerScrewHoleSpacing = 64 portLocation = back driverVas = 1.132 enableClosedBoxCalc = no boxThickness = 11 portYOffset = 0 terminalScrewHoleSpacing = 61 portXOffset = 0 numberOfSpeakerScrewHoles = 4 speakerScrewHoleDiameter = 3.25 numberOfTerminalScrewHoles = 4 driverQts = 0.68 portWallThickness = 5 portLength = 100 terminalHoleDiameter = 50 portInternalDiameter = 20 boxDepthRatio = .8 makePort = no boxWidthRatio = .95 terminalScrewHoleDiameter = 3.2 terminalType = terminal cutout wireDiameter = 2.2 boxHeightRatio = 1.1 boxQ = 0.9 showSpecs = no
