The Spruce300 Toolhead A with its rubber pads and cover variants works well but can be fiddly to set up.
This much simpler design prints as a single part and allows many different bearing configurations, including the stock 3 LM10UUs, 4 LM10UUs, or use of an LM10LUU (long) bearing on top or bottom.
NON-PRINTED PARTS:
6x M3-16 socket-head screws
3x M3-12 flat-head/countersunk screw
5x M3 nuts
6x M3 threaded inserts
I sealed the holes for the clamping screws so the surfaces touching the bearings print smooth. You will need to drill them out with an M3 or 1/8" drill bit.
Only install clamping screws at bearing centers. For example, I use the carriage with 4 LM10UU bearings in the 4 corners, and do not install the 2 center screws.
The Spruce300 Fan Duct is also compatible with this model. If you are using a standard E3D style nozzle and install a bearing in the lower center position, you will need to use a button-head (rounded) screw.
