Assembly Notes:

1. Print out the STL models.
2. Insert magnets with a small amount of CA glue.
3. Insert the brass inserts into the models.
4. Attach the weather strip to the Brush Pallet. The weather strip I used had an adhesive back, however included holes on the brush pallet to allow the stripping to be secured using a nylon thread. After securing the adhesive strip with the nylon thread, place a drop of CA glue bound threads.
5. Assemble the parts grouped in the Openbuild Mount Assembly folder. Next, mount the assemblies to the OpenBuild Spindle Mount.
6. Assemble the parts grouped in the Spring Assembly folder. Once the plunger is assemble screw it into the Plunger Pallet Mount.

Overall Impression:

This dust boot worked well for me, prior to updating my CNC to a spindle. It provided me the ability to adjust for multiple cut plans and quickly change out bits by removing the pallet. My only criticism was when it came to adjusting the height, I feel I should have arranged the latches to allow additional clearance.
