Grinder for the battery of the Makita. Printed PETG from FDPlast, layer 0.3, filling 30% triangle. M4 screws. The engine DPM-30-n1-01, was available. Bearing-3 pieces unknown: external -14 mm, internal - 7 mm, height 4 mm. The tape is 330x15 mm, ordered on Ali. The toggle switch is round, although a rectangular one would stand up without problems, but it seemed to me that a round one would be better. The power connector is cable, without a housing. Contact plates for the battery 32x15x0.5 mm, I found a sheet of copper in the bins.
Since the grinder was designed manually, and then a platform was attached to it for the battery from the Makita, another cable is needed, short with two dads, there are two power outlets with different polarity on the site, so the reverse was implemented.
I don't have a branded battery from a Makita, it fits my Chinese clones.
