Lid for Seneca River Trading Glass Blender Jar (for KitchenAid K400 replacement)
thingiverse
You'll find it next to impossible to find a replacement jar/jug for the popular (but discontinued?) KitchenAid K400 blender (aka KSB4027). I found a nice heavy glass jar replacement from Seneca River Trading Company (https://senecarivertrading.com/glass-blender-jar-assembly-fits-kitchen-aid-ap7014452-ps16543616-w11528690 ) but it comes without a lid, and the original KitchenAid lid doesn't fit. Seneca River also offers the lid (for about $30 more plus shipping) but they are out of stock, and there don't seem to be any more coming. The new jar is pretty useless without a lid, so I designed and printed one myself -- and it's working pretty well. I included a small depression in the circumference for a thick elastic band to help as a simple seal. I'm including the Fusion 360 file in case you want to tweak it for yourself.
