A standard length for camera trays
The upper frame of the Titan 2 Rig now fits the trays from the Redstone Rig (left) as well as the big dual-camera tray (right).
Recently I tried enlarging the Titan 2 tray and found that there was indeed a little more space on the build platform. It pushes the limits, and I assume the temperature of the plate is not as high right at the edges which could compromise adhesion to the plate. But the printing seems to go well when I put plenty of glue stick at the corners. So I enlarged the upper frame which is now the same width as the Redstone frame. The two frames still differ in another dimension which makes the Titan 2 frame sturdier (it has to support two cameras). I considered standardizing on just one upper frame for both rigs, but that would make the Redstone Rig heavier, so the upper frames are still distinct.
The advantage of the new width standard is that Titan 2 users can easily turn their two-camera rig into a single-camera rig by installing a Redstone tray. In fact, every Titan 2 Rig sold here includes a single camera tray in addition to the big dual camera tray. So in effect, when you buy a Titan 2 Rig, you also get a Redstone Rig.
If you print your own Titan 2 tray, make sure the corners are well adhered to the build platform. The part probably cools fast at the far corners of the platform, and a couple of mine have curled up which can make the tray unusable (the tray lip becomes curved and it’s then hard to mount the cameras so they are pointed in the same direction). Two of the three camera platforms on a curled tray are still usable, so maybe these Titan 2 trays will be in a KAPtery seconds sale some day.
