Inverter / LDU 3D printed tools

Post by Zoti »

As part of the work we do at the shop I found that it's best to design some tools to make things easy to do the work.

Below, a few of the tools I designed and 3D printed.

Inverter stand - No need for wooden blocks or screwing the inverter down for stability.

This is a set of 2 stands to place the rotor on for cleaning.

A set of caps to seal a coolant flange after we did a coolant delete on it. You can then blow some air into it and test for leaks at the new seal.

Here's my setup for cleaning the stator

I actually sell these (not trying to advertise. Just explaining why I don't release the files). I have some other misc tools that are simple and I share. I'll post them.

Neat, thanks!

Here's an LDU inverter stand I made: https://www.westside-ev.com/s/LDU-Inverter-Stand.stl

Just connect two of them to one of the three metal phase support structures and lay the inverter on its side. Way more stable than vertical.

I completely forgot that I actually shared the inverter stand already. Here's a link to the file.
