Pretty happy with this case. Even though I need to widen the wiring channels a bit it feels super solid. I mounted the 3 vibration motors separately from the heaters so they would not contact. These motors seem to be good up to about 60c, which isn't a goal temperature but I don't want to wear them out by letting them near a fluctuating PID heater. I'm using two of the larger kapton heaters that Adafruit stocks, but there's enough room in there for other types of heaters, especially if I find a better solution to routing the wires in the heater. A DS18B20 temperature sensor is touching the heater (visible in the second to last image through the plastic). I'm also running lube into this, all via a single bundle out the back. Wire bundle has pretty good strain relief due to the PTFE tubing. Silicone 5mm OD 3mm ID was the intended tubing, but I can't find mine. Oops.
Update on the mount, I'm needing to restructure the whole build because of too many joints between the servos and the desk. Lots of adapters make the whole thing a bit too wobbly. Learned a lot on that version however, so I do intend to get back to it after this is done.
