Fully 3D Printed Speaker V11-Project Metal Heart

thingiverse

This is the basic components of a 3D printed speaker; you need to add magnets and copper wire, Along with getting the 4 plates cut from a local or online laser cutter. The Surround should be printed in TPU or this speaker may not work. I used Varioshore Foam but it should work with everything from 85A-97A it will just change the frequency response (higher shore hardness = high frequency response-- 85A will act like a small woofer and 97A should act like a mid) Magnets are as follows 8 - 12.7mm (½") diameter by 9.7mm (3/8") mm height - n52 *** MAGENTS OF THIS SIZE CAN START TO BECOME DANGEROUS, THEY CAN SHATTER IF LET FLY TOWARDS EACH OTHER, AND CAN ALSO PINCH AND CUT SKIN, ESPECIALLY WHEN USED WITH SHARP LASER CUT STEEL- USE THESE DESIGNS AT YOUR OWN RISK - WEAR PROPER PPE (Personal Protective Equipment)*** also need: 7-3mmx14mm screws 4-2.5x8mm screws 4-4mmx10mm screws Copper wire is magnet wire with a .3 mm OD i used enough to set it up at 3.7 OHMs you'll have to check your manufacture spec of wire for OHM per 1000 ft and then do some conversion math to get your desired OHM rating. I Also used a coil winder to get a smoother and cleaner coil wrapping, you can do this by hand it just takes longer. --MAKE SURE YOUR AMP IS RATED FOR THE OHM YOU'RE WIRING FOR-- you can always wire higher than your amps rated OHM but never lower. Magnet bodies should be printed in PETG as they can get warm. The Cone was printed on a resin printer due to the thin walls. (Use FDM at your own risk) everything else (minus surround steel plates) can be printed in PLA,PETG,ABS etc. The DXF file (back plate for laser cutting) is for the back of the box-it can be imported into a 3d model software and extruded if you want to just print the back. the other dxf models (Upper Middle plate POINT 25 PLate,Bottom Plate POINT125 plate,Lower MIddle POINT25 plate, and Upper mounting plate POINT125) all should be cut from mild steel - (the Point125 = .125") indicates thickness for the plates Video Link: https://youtu.be/v8OEhhKK1UQ
