About this 3D model

For those building Kossel Minis, this is a modified carriage frame that allows you to use standard 12mm low profile carriages like the IGUS DryLin® T - Low-profile guide TZ-04-12 series. This will also work woth PMI MSC 12M rail, and I suspect HiWin as well - really any car that has 15x20mm mounting holes. As an added advantage, I replaced the "block" style belt retention on Johann's carriages with a GT2 tooth profile to allow you to use an open loop belt.
