Remix of the original assembly with raised internal height so no lathe work is needed.

Update 2: Over Christmass break I was able to button up everything. Sadly I couldn't get the encoder to work (my encoder was not working correctly, the design is not the issue), so I switched to Tig33r's magnetic encoder design. Now everything is assembled and finished. The magnetic encoder has also the advantage of freeing up space on the side for DC-DC converters (if you don't use 24v van) or possibly the relays recommended on the FFBeast discord server. Later on I might design a holder for this.
Update: I printed and built mine, along the way there were a few things needed fixing but I uploaded the updated files. Mechanically everything works, I just have some electrical gremlins left.
The Original design requires you to remove some material from the outside of the motor to make it smooth, this often requires access to a lathe. I wanted to remix the files so that you can use the motor as is.
The covers are raised 5mm and the raiser part is also slightly higher. I tried to model my motor in CAD and it fits but I don't know how big of a variation are there in these motors tho. The whole assembly also needs to move back a couple of millimeters to make space at the front cover.
Also included is an alternate motor controller holder. I printed and tested on mine, it doesn't have the strongest hold but it works fine and doesn't require any drilling like the original.
The connector for the brake resistor wires are a tight fit, this was an oversight on my part. I used crimp ferrules and just bent them slightly to clear. Without ferrules you would have more clearance and don't need to bend.
On the Odesc 4.2 the heat-sink doesn't have through bolts. If you have a different controller with the ability use through bolts a different holder that utilize those would work better.
For the printable riser:
The holes on the side are sized 4.5mm for 5mm OD melt in inserts (M3)
To hold the encoder and motor controller holder to the riser M3x10mm bolts are needed
For holding the sk16 to the riser you need M5x50 bolts and nuts (you might be able to use slightly longer too)
For holding the riser to the 4080 you need M5x50mm bolts also and T nuts
You also need a 200mm gt2 belt (as per original design, it's a tight fit but provides good tension, slightly longer could work too) and a spring for the encoder holder (original used 3d printer bed springs, I didn't have a spare so I used a 8x30mm I think with 1mm wire, max external diameter is 10mm)
