Speaker Spacer Ring Generator

cults3d

This is a speaker ring generator to make speaker rings for car audio or for home audio applications. It's a remix from the parametric speaker generator https://www.thingiverse.com/thing:451253, mainly for the speaker mount holes. I believe you can make 3D printed speaker spacers better than a lot of thin ABS commercial spacer's and being plastic they have the added advantage of being water proof unlike MDF speaker rings. The default speaker ring size is 6.5 inches. Use to make speaker rings for 1, 2, 3.5, 4, 5, 5.25, 6, 6.5, 6.75, 8, 10, 12, 15, 18, 21 inch speakers (well obviously the sizes are dependent on 3D printer capabilities, could go with CNC for larger sizes). For instance on an Anet A8 with 220 x 220 mm you could print up to the 8 inch size, on a Crealty CR10 with 300 x 300 mm you could do 10 inches. There are some printers that could go up to 400 x 400 mm and you would be able to print 15 inch rings. When using the customizer I find it works better if numbers are entered as "8.0" instead of "8". You will need the speaker cutout hole size, the speaker mount screw width from center to center, the car mount screw width from center to center and a measurement of the maximum diameter you can make your speaker ring. Some may need a bracket mounted to the outside of the spacer instead of integral to the spacer. In that case I recommend the parametric L-bracket Thing https://www.thingiverse.com/thing:2226 as you can now select the length of each side of the bracket. Could be attached with a small screw and some adhesive. Or breakout your favorite 3D modeling program and combine the brackets with the ring. Update 8/11/19: Made the change suggested by rshambaugh in the comments. Update 6/28/18: Some minor updates. Screw mount holes set to 75% of height. Update 5/25/18: Made mount screws inset into spacer. Update 5/24/18: Set mount screws to 0 degrees. Added an angle variable for the speaker screws. Default is 45 degrees. Update 5/23/18: added a trim ring for flush-mounting. Cleaned up the screw holes so they are round. Speaker screw holes go halfway through, mount screws go all the way through.
