Tekton compatible socket holder for 1/4" drive sockets.  Two sizes of socket nubs to handle different brands of sockets, easy to file off a few thou with a nail file.  This is a “tight” print so use your best resolution and your most bendable filament, I printed mine on a Bambu X1C, .4 nozzle set at “.12 fine”.

They will wear a bit as they break in and eventually wear too much, but trivial to print out a replacement.

Note that these are standard socket holders, not the Tekton style that rotates on/off.
