These are the kits available for (pre-)order so far: 【Pre-Order】ZXB-01A Roller for WFC Earthrise Optimus Prime Upgrade Kit 【Pre-Order】ZXB-01B Upgrade & Weapon Kits for WFC Earthrise Optimus Prime Upgrade Kit 【Pre-Order】ZXB-2 Weapons for WFC Siege G2 Black Sideswipe Upgrade Kit (Painted) Copied this from EAT: Finally received the ZXB-01A Roller and laser gun barrels kit for Earthrise Optimus Prime in the mail today. Took a little under 3 weeks to receive in the mail from TFSafari with their newer shipping method. Ignore the blue repair drone custom...that's mine. The overall 3d printed quality is the 2nd best I've seen. GX Studio looks like injection molding. This is just a step under that but much better than Matrix Workshop and Shockwave Lab. This is the first time I've seen 3d printed transparent plastic turn out well. There is a QC issue with the pegs in general: they're all painted over. This appears to be a rookie mistake. So, if you don't want paint getting into your blast effects or into the repair drone ports, then you need to sand / file the paint off. One of the laser barrel pegs was also a touch too big and needed to be filed down (5.15-5.2mm was on one peg but the other was 5.05mm). It was trickier getting the painted file off the side of the blast effects pegs. Fortunately, they use gray as a base plastic, so it actually looks fine with the paint filed off the pegs. The silver paint actually matches the gray stock plastic. I was surprised it did. This is the laser barrels attached to the stock repair drone. The shows the under view of Roller. Paint job is well done. Actual screws are used to hold the thing together. Wheels are all pinned and, um, roll. This shows the varied colors used. The ports and red light are transparent printed plastic. Not shown but there is slots for very tiny figures to sit in. I don't have one at that scale but I may have tiny Gundam humans still on a sprue somewhere. This shows the print lines when viewed way up close. Even the headlights are made from the transparent plastic. Nice touch. Looks good transporting the trailer. Overall, great set. Be prepared to file / sand down paint off the pegs, though, and one of my laser barrel pegs was oversized. I'll send that feedback to TFSafari and see if they can send that back to ZXB. I have the weapons kit for ER OP pre-ordered and hoping that will turn out just as well. I used a flat precision file to easily get the paint off the pegs.
