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:

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.

"Open Inverter is a community of people and projects focused on
open source solutions for EV conversions"
Merriam Webster
open-source,
adjective
1) having the source code freely available for possible modification and redistribution
2) publicly available for use by the community at large
I do not begrudge someone having a company and selling a product. I am a capitalist. But this section of the forum is for sharing information about open source solutions. If you want people to know these are available for purchase, that is what the
Classifieds section is for. Sharing something cool and then going "but I won't share how" runs completely counter to the purpose of the forum.

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