I know there are several test lead holder prints available but after using them with a large amount of banana and 3.5mm modular cables, they usually broke under the strain or couldn't hold as much as a Pomona steel holder. This model is a multiboard mount for a Pomona test lead holder. Because Pomona's holders do not match the sizing for multiboard, I made sure to only partially cover one socket leaving all other socktes on the multiboard available. 

These mounts can be printed without supports in the orientation provided, please use the multiboard standard (3 wall thickness, no support, print in original orientation) Because the tabs of the support snap and mounts start out very thin and detached from the main body, a 2mm brim will help with bed adhesion. 

Happy printing, happy patching.
