Copymaster 3D 300 brace bar brackets

thingiverse

Brace bar brackets for the Copymaster 3D 300. Bars are offset outboard to avoid getting in the way of the Z axis. NOTE: I altered my Copymaster 500 bracket design and didn't check Z axis clearance. I have checked now and nozzle can go 392mm from magnetic bed before the brace bars get in the way. It will be less with a glass bed! If anybody needs the full 400mm height let me know and I will alter the brackets. Other parts required: 2no. 644mm lengths of 2020 aluminium extrusion. 18no. M4 x 8mm socket cap screws. 18no. M4 T nuts. The bars are at 22.7 degrees from the vertical. Instructions. Install all 10 T nuts in printer frame Cut one end of a bar at an angle of 22.7 degrees. Fit bottom bracket to cut end of bar, only lightly pinch up bolts. Temporarily fit the corresponding top bracket to the printer with one bolt. Place the bar in the correct position and mark the bar for cutting length. After cutting to length remove top bracket from printer and fit to brace bar loosely. Fit brace bar assembly to printer, install inboard bottom bracket bolt first to avoid bolt heads clashing. Tighten the bolts that hold the brackets on the bar last. Repeat for other side. Edit: added a filament clip for 2020 section which means you can have the filament detached from the spool and near the extruder ready for swapping over when it is up to temperature.
