Power Distribution Post M10

thingiverse

This is a DIY version of a power distribution post for big power cables, originally designed for marine applications but easily adaptable to automotive use. It consists of three printed pieces, crafted with a blend of good intentions and limited practical experience. The inner piece performs best when printed upright to ensure strength in the vertical pulling direction. In contrast, the outer piece is meant to be printed flat, preferably upside down, to accommodate supports and tolerances. Its purpose is to provide resistance to the layers of the inner piece coming apart when the bolt is twisted. Update: The STLs have been revised to position the parts in their optimal orientation. All components fit together seamlessly on my initial print at 0.20 layer resolution with a .40 nozzle. Some minor tolerances have been taken into account, but you can adjust them during slicing if necessary. No snap fitting is employed; instead, glue the bottom cover for added security. Required non-printed parts include: * M10 bolt (M10x30 is an ideal size) * 2 M10 nuts * M10 spring washer The mounting holes are designed for M5 bolts (hexagon socket specifically), ensuring that power cables cannot come into contact with these when using metal bolts in a metal body. New: The first draft of a cover has been created, inspired by the design of store-bought posts but modified to suit 3D printed applications. Key features include non-rubber materials and screw-fitted instead of clamping designs. Two versions of the cover are available: one slightly taller than the other, allowing for more threads engagement with the bolt. However, I would like to incorporate a slot-in cap for the post cover to seal off unused openings. This design remains a work in progress for now. I recommend using a longer bolt when connecting multiple terminals, as it's relatively easy to stretch the legs of the cover. I look forward to seeing your creations and hearing your feedback!
