These are 3D ready models to print. Used to keep your cable connectors (LEMOS) from touching eachother, organized, and stored safely.Designed for fischer 102 A051-139 & 103 A053-139G, but can be used to store and seperate multiple cable connector sizes to protect against visual defects.This kit includes the fallowing:1.) A single connector holder model for size reference.2.) A full tray which holds x25 per tray. Fits 3 x 4 in a standard 12 by 16 inch box. (300 connectors per box)3.) These connectors (102 A051-139 & 103 A053-139G) come with a brass o-ring. To tighten I designed an adapter that's standard 1/4th.The only model that needs supports is the adapter.All models come with a STL, OBJ, & STEP file format.
