These 3 items are all specifically designed to work with the Ryobi 18v One+ Compact Brushless Blower Model #PSBLB01. All of these items simply pressure-fit or clamp on to the blower and no tools are required to install them. They're also easy to remove. Available here as individual parts.

AIR INTAKE COVER: This partially covers the air intake vent of the blower to redirect and disperse airflow around to the sides so that your clothing is not so easily sucked in. 2 tabs pressure fit into place and no tools are required to install it. If you do not wish to use it all the time, it can be stored by simply pressing it onto the top (rubber) hump of the blower of which is stays securely. Edges are mitered and smooth. The overall shape is similar to the blower.

ACCESSORIES HOLDER: Since the blower comes with 2 extension tubes and a flat nozzle, this accessories holder allows you to store and hold these 3 items on the blower itself. It simply clamps onto the tube on the blower and has 2 more clamp rings to hold the extension tubes. There's a twist-lock ring to hold the additional nozzle that's not in use which includes recessed triangle markings (similar to the blower's shaft) for alignment. This assembly can be mounted above OR below the main shaft of the nozzle per your preference. See photos. The blower can still function and the handle with trigger are still accessible while the accessories are attached.

STUBBY TURBO NOZZLE: This additional nozzle focusses the airflow to get a more concentrated blast of air. It twist-locks to the blower the same way other nozzles attach and includes recessed triangle markings similar to the Ryobi nozzle. It is rigid plastic with a thickened & beveled edge at the tip.

The Ryobi Compact Blower PSBLB01 is NOT included and shown in photos for reference only. The extension tubes and flat nozzle are NOT included either (since these come with the blower). No batteries, Ryobi Link Wall Rails, nor other tools holders that are shown in some photos are included.

The Air Intake Cover and Stubby Turbo Nozzle do change the air flow through the blower. Use these at your own risk and seller assumes no responsibility to your blower by using these accessories.

These are uniquely designed and 3D-printed by the Seller in the USA. Items are lightweight and 3D-printed in PLA plastic. Due to the printing process, there may be some minor imperfections which are mostly likely to be on the bottom/back side, not exposed to view. PLA plastic is made from a renewable resource and is biodegradable and eco-friendly. 3D Printing involves the heating and depositing of material on a flat board one layer at a time, thus most exposed sides have small, fine lines. Infill (non-exposed) areas are not solid plastic.
