enclosed jacks in madbean eagle libraries

[add4]

I'm looking at enclosed jacks that have the same configuration as those in the mad bean libraries.
Basically the ones i bought have a few millimeters of plastic along the shaft of the jack, this thing prevent them from going in their pcb pads.
So i'm wondering where i could find the parts corresponding to madbean libraries (mb_jacks_alt -> stereo_pcb)

I found this http://www.musikding.de/product_info.php/info/p1160_6-3mm-Wah-Stereo-jack-metal-hex-nut--print.html but 3.5 euros for one jacks is a bit hard to digest.

I also started making a new eagle device corresponding to the parts i sourced, but i'm not sure they are very sturdy anyway, so i might change.
