Revision 2b of the motor mounts are attached below.
They are in a .stl format.
There are two versions of each piece, one Imperial and one Metric.
You will need a single main mount and two plates to complete a set.
Every 3D suite and slicer seems to have a different coordinate system Some use Y as up or Z as up.
The main mount should have the motor bolt countersink's at the top.
The mount plate is just a flat plate.
Settings I used in Cura for my original prints which worked good.
1: I used a .6mm head
2: Default three pass wall thickness with no infill.
3: Default 1.2mm top and bottom thickness.
No support material or brim. I do not know how they all work, but the ultimaker can in fact print over small voids without supports and it handled the mount with no issues.
This is a second revision, but still a beta. I have not actually printed these yet to test them, but I can not imagine the changes I made broke anything.
I will be printing a new test set tomorrow if you want to wait. I am uploading these for
@kilroy07 though so you do not have to wait until tomorrow to get started.
