I made this model to fit the Two Trees vacuum system on the 800W spindle that came with the CNC machine, a TTC 450 PRO by Two Trees because unfortunately the stock one by Two Trees only fits smaller spindles.
I reused the LED bar from the original part, you are just gonna need to drill 3 very small holes (I drilled 1 mm holes) for the three front screws close to the USB plug and reuse 4 of the 6 magnets to hold the bottom part in place.
Unfortunately the short original brush need to be trimmed down a little in order to sit flush with the milling bit.
Printed with PLA with support material for the upper interface, 4 walls, 30% gyroid infill, 4 upper and bottom layers.
I added two holes for 4 mm diameter threaded inserts in order to use two screws to hold the adaptor in place on the spindle.
The author marked this model as their own original creation.
