These Alligator Holders are for being used with the PCB workstation featured here http://www.thingiverse.com/thing:801279. I modified the alligator holder part to be used with regular and mini alligators that can be bought from electronics parts suppliers.
The 5.2mm version works with these part numbers:

The 4.4mm version works with this part number:

The diameter is tight enough to prevent the parts from comming off. You may need a hammer or a heavy tool to insert the alligators inside. I also modified the hole diameter to allow a dupont wire like this one http://ep.yimg.com/ay/yhst-90268561309754/awg26-30cm-dupont-wire-color-connector-cable-3.gif to pass trough.
