Ultimaker 2 - metric or imperial

Recommended Posts

Posted · Ultimaker 2 - metric or imperial

the screws are almost all standard M3 screws (I think that means 3mm diameter). The lengths are all in mm. Typically 5mm, 10mm, 12mm, 15mm and so on. Someone recently posted what you have to search for in mcmaster carr to find them with the same screw head - they have a weird name.

From a random ebay ad: "HEX SOCKET BUTTON HEAD ALLEN BOLTS SCREWS SCREW ISO7380". The "iso7380" part will get you on the right track alone.

However, there is one difference worth to mention as far as i know:

Bowden tube and fittings are imperial. Metric dimensions will only give you 3 mm or 4 mm inner diameter. The latter is quite loose, the first is too tight. Ultimaker uses an imperial size tube with a 3.somerhing inner diameter.
