Copymaster 3D 500 brace bars

Brace bars for the Copymaster 3D 500. Bars are offset outboard to avoid getting in the way of the Z axis.

Other parts required:
2no. 800mm lengths of 2020 aluminium extrusion.
18no. M4 x 8mm socket cap screws.
18no. M4 T nuts.

The bars are at 30 degrees from the vertical so cut the ends at 30 degrees.

I like this printer due to its build volume and direct drive extruder however here are some handy tips for Copymaster 3d 500:
For better surface finish when using PLA modify the fan shroud on the printer head so no air blows on the part being printed. You can't just turn it off because the same fan cools the extruder.
I use a glass bed with 3DLAC, the bed heater only covers the centre of the build area on the 500 so I use a higher bed temperature than I do on my other printers, 50 degrees seems to work ok so far for PLA.
I don't route the filament through the thing that senses when filament runs out as I think it is mounted too close to the spool. I pop an offcut of filamen
