BIQU B1 spool holder angle adapter for direct drive
Description
I wanted to design a simple adaptor for mounting the stock spool holder of B1 in 90° angle for direct drive configuration. Mount this piece to the back side of the gantry using M3 screws and T-nuts, then mount the stock spool holder on top using the stock m4 screw on the adapter without the t-nut, there are M4 threads in the model for the screw, which may or may not need cleaning with a tap depending on how well your printer is dialed in. Mount the other side to the frame V-slot using the stock M4 T-nut and screw. Note that i am yet to do extensive testing with this adapter, to find out if it causes Z-wobble. However i think, that a spool holder with a bearing is beneficial with this thing, to avoid wobble. I suggest using the Filler spool holder, the Ender 3 version fits the B1 stock spool holder bracket. Mounting hardware required: 2x M3x25mm cylindrical head screw (head diameter max 6mm) 2x M3 T-nut (printed or from spares bag) 2x M3 nut (if using the printed T-nut) 1x M4 T-nut from stock spool holder 2x M4 hex screws from stock spool holder, though i suggest using a longer one on the printed part to avoid stripping the printed threads.
