HEVO x- carriage with alternative belt clamp & tensioning

thingiverse

As an alternative idea I redesigned the clamping and tensioning mechanism of the x-carriage for the HyperCube Evolution. Made it easy to print. You need one X-Carriage_Front, one X-Carriage_Back and four Belt_Clamp's. The belt clamps have recess for M3 nut and screw and below a slot for the belt. They can be used on both sides of the Front part of the x carriage. The pictures actually show what to do and are explanatory . The tolerances are very tight. The holes you end up with in the front part are due to the minimum nozzle size. (I used .4 mm so it will not nicely close the hole during printing). However this is not a problem as everything slides nicely next to each other. Things to consider when printing: - Print everything with facing the heat bed as logical. Make sure you use supports for the Belt clamps but from the heat bed only. (if you don't U end up trying to get the M3 holes clean with a lot o effort) - Use 4 vertical shells (Perimeter) as this will help rigidity. - Personally I use mouse ears to make sure the faces remain flat on the heat bed during printing. I am open for suggestions. Next project is to design a x-carriage based on this design with very short nozzle to x-axis length. This minimizes the fault caused by to heavy carriage weight and vibrations. Any suggestions are welcome. I also considering building a tool to measure belt tension in order to adjust this easier and not based on 'good feeling' Suggestions are welcome also.
