Package was surprisingly small when you consider that the rails are 4x300mm. They were set in foam and packaged diagonally, no dents or scratches. X carriage plate holes seemed too short, M3x16 should be used, but the holes only fit about 13mm, not too big of a deal though if you are an RC hobbyist and have plenty of countersunk screws. May have been just a fluke with mine and nothing that would even require rework. -Nice to see that the Y belt includes some extra length, so custom belt tensioners can be used. ! Make sure they do not exceed the top of your 40x40 extrusion though, the belt mounts need that space to move Currently doing a calibration cube Also half the cost of the Amazon full BLV kit.
Fast shipping, well packed. Absolutely nothing missing from the box and all the anodized parts are perfect.
