Optimized Makita RT0701C Mount for MPCNC

thingiverse

I designed this mount to place the Makita as close to the z-axis as possible without compromising stability or making installation or adjustment complicated. This design utilizes the standard mounting plate from Allted. Most other Makita mounts on Thingverse space it unnecessarily far from the z-axis, but after some CAD work I was able to create a design (blue mount above) that places the endmill only 45mm from the universal mounting plate, approximately 1.5 mm closer to the axis compared to standard DW660 mounts (red mount above). Furthermore, I discovered that many mounts on Thingverse feature small "wings" where screws attach. While this facilitates easy access, it generates stress concentrations that will cause clamps to fail prematurely. I positioned bolt holes in line with tensile forces of the clamp to minimize these shear stresses. Parts List: 9 x 6-32 3/4" machine screws 9 x 6-32 nylock nuts M4 nuts and screws can also be used, but you may need to drill holes slightly larger. Printing Recommendations: I recommend using PETG filament. PLA might work for a while, but the heat of the router combined with vibrations during cutting will likely reduce its lifespan.
