Motor module 2 electric boogaloo??

Ok so, a friend told me to make some motor modules out of sheet metal. This is a good idea! Unfortunately I think it is out of budget… but it is nice to have around!!

Anywho.

Start with the same layout as before.

Create a motor side plate. This plate is not thick enough for the bearing on its own - it will need stacked with another. That makes these motor modules 3 plates each. 3 times 6 is 18 plates total. Youch, my wallet.

Extend it and create a matching idler side plate. This plate can be thick enough for the bearings on its own, so it won’t need stacked. This is good for budget.

There’s that second stacked plate. Each thin plate is 0.1”. The thick plate is, you guessed it, 0.2”.

From there I made these simple printed part structural spacers. These are designed to be minimal at the top so I can still hopefully route belts. I think it will be difficult to route belts in this design no matter what I do, but this could help.

Last, I just add screws and nuts that go through the whole sandwich. This is the easiest and most rigid way I could think of assembling. And I think it turned out really nice!

It’s just… these would add $200-$250 to my budget… I think I would rather bulk up the printed part. So that’s what I will do next entry - bulk up the printed version! It is such a small part that I think it is fine - end to end, this thing is like, 110mm. So it really shouldn’t matter much.

Actually, one last thing.

This cutout will help a ton with belt routing.

Ok that’s all for real this time.
