Simple spool holder for Mendel or any other reprap printer
Status: testing.
Description: Originally designed for my reprap sinuhed project. It is easy to make if you have access to drill a small home milling machine. The cost of input material is low. Published documentation is for sinuhed and Mendel project. Most parts are similar. Main difference is size of alluminium plate and position of heating elements. Compared to Table from printed circuit board this table achieves greater thermal Stability.

Wiring
6R8 resistors Preffer wired or vitreous resistors for 2 or 3W. They must be stable at 150°C. For one table u will need 18 resistors. Resistors need to be connected according to the drawing. The resulting electrical resistance is 1,51 Ohm. (I we ignore electrical resistance of wires). For 12V we get approximatelly 95W of electrical/thermal power.
5R7 resistors U will need less amout of these resistorsat the expense of a bigger load. (possibly shorter life of resistors). U will need only 16 resistors. Resulting electrical resistance will be 1.425 Ohm. For 12V we get approximatelly 101W of electrical/thermal power.
In both cases standard PC power supply with 15A on output, for whole reprap, should be enough.
