Do you crave that thumpy 60's Carol Kaye flatwounds-with-felted-bridge sound but hate the look of having random pieces of foam/felt taped or wedged into your bridge?

For certain kinds of bridges often found on Epi/Gibson style basses (e.g., this bridge: http://www.allparts.com/BB-0333-001-3-Point-Bass-Bridge_p_566.html ), I designed a slide-on bass mute. Just print 'er up, stick some felt/foam along the inside top, and slide it on! It's not exactly "pretty" but it's not bad, and (perhaps more importantly) it does work...

I dunno what kinds of tolerances these things run, so please measure and scale up the dimensions accordingly BEFORE you print. The files I uploaded here, assuming nothing strange happened to the dimensions during export, happen to fit snugly on my Epi Jack Casady (basically a re-issue les paul signature) bass...

also, included is a "no-logo" version so you can stick whatever else you might want to stick on there. have fun!

PPS i got greedy and pulled the mute back off of the bass to give it more and more coats of primer - the penultimate shot is the finished mute after a couple more coats...

At my replicator 2's default medium settings, I had a little squirrelly-ness on the little logo overhangs (I printed these with the top-side logo facing out the front side of the machine), but I got pretty decent results with the medium, .2 layer thickness, and 3 shells settings.

For my Epi Jack Casady bass, ensuring (with uniform scaling) that the X-axis width (of the exterior) was 100 centimeters seemed about the perfect amount of snugness.

Hi all, just wanted to let any potential downloaders know that unfortunately this did not work for me... I have a 2014 Gibson SG Standard Bass, with the 3 point bridge, but alas when I had this printed it did not fit my bridge, this could be because my 3 point bridge is bigger than than the Epiphone 3 point bridge. However, this has encouraged me to get the dimensions of my bridge and change the design so it does fit. This is a really awesome idea from hewsonchen!

awesome, i hope you can scale it to work on the gibson bridge without too much trouble... i've only tried it on epi bridges so definitely good to know that the gibson dimensions are slightly different. thx for the heads up!

love this. I have a casady bass myself so will definitely give this a go (if I ever get a 3d printer!)

oops - just noticed i had failed to upload the photo of the mute after a few more zaps of primer/filler... just uploaded that, along with a shot of the underside of the mute to show the 'bicycle helmet foam' padding. conventional wisdom would seem to indicate that crafting felt would work the best, but (after trying a lot of different things) i am really having best results with the stick-on bicycle helmet padding foam that you see in the last shot.
