Festool Cleantec Dust Collector Adapter for Bosch Random Orbital Sander

In order to create a very stable connection, I used four components:

• Two 3D printed parts (the adapter and a support block)
• A spare 5mm Allen key cut to a length of about 70mm
• Plastic tie straps

Adapter assembly (see notes on pictures for further explanation): The dust bag retainer on this sander has a tongue that slides out and connects to the removable dust bag that came with the sander. Between this tongue and the base of the sander handle is a slot to store the 5mm Allen key that came with the sander. The adapter is designed so that both the tongue from the dust bag retainer and the 70mm long section of the Allen key are inserted into the adapter to hold it in place. The support block is then added along with the plastic tie-straps to secure the adapter.

Usage Warning! Only use this adapter on this sander if your vacuum has a low suction level setting! There is a circular rubber seal inside the sander (between the rotating pad and the sander body). If the suction level is too high, the seal will come off the lip it’s mounted to and then create a lot of friction while the sander pad is rotating. To fix, you need to remove the sander pad (with the Allen key) and then remount the seal onto the lip.

On my Festool vacuum, I turn the suction level down to its lowest setting and it does a great job at dust removal.
