Do you need anything we don’t have? Request it! Initially intended for scale model makers (Boats, Aircraft, and Toys), we realise that there is always that person who wants to spin something too fast or too violently to be considered responsible and safe. Too fast is anything that causes the structural failure of the component being spun. Anything too violent includes small internal combustion engines and electric motors of sufficient power to cause structural failure upon start-up or when reversing direction. Propellers/Fans/Impellers can become projectiles if not properly fastened and/or contained in a suitably strong containment shroud.

Please read the following cautions very carefully and in earnest.

WARNING! WE RECOMMEND THAT THIS PART BE USED WITH EXTREME CAUTION TO AVOID SEVERE INJURY AND/OR PROPERTY DAMAGE!

Rotating parts can disintegrate when rotating at high speed and under load. Pieces of this part travelling at high speeds can hurt or potentially kill someone. Please use extreme caution and never place yourself or anyone else in harm’s way by using this printed part in a hazardous way. Minors must be accompanied by an adult when using this part in its intended or unintended fashion. We are not responsible for the poor judgement of our customers or the general public. 3D printed parts are not as strong as similar injection moulded, cast, forged, or machined parts. All “3D-printed” parts made from plastic are prone to failure much sooner than traditionally manufactured plastic parts made by “printed” methods.

    ACE-One, Propellers, 6″ x 5″, 4mm Shaft<

    A pair of attractive/efficient propellers intended for small projects. Products feature highly efficient airfoil sections for low Reynolds numbers (small propellers). Aggressive pitch moves large amounts of air. Designed to fit on standard 4mm shaft motors (CW and CCW). Intended for use on Multi-Rotors, Airplanes, Airboats, Hovercraft or Blimps. See below for more model details about this genuine STLhive.com part.

    Ducted Fan Unit, 3″ (MT1306)<

    This small Ducted-fan assembly is to be used with the following motor and fan: M: http://www.rctigermotor.com/html/2013/Professional_0912/41.html F: http://www.stlhive.com/shop/aviation/fan-3-x-2-4-4mm-shaft-mt1306/ This complete design is intended to be used with Hovercraft and Airboats. It is suitable for aircraft use (Multirotor, Airplanes and Blimps) but it is probably a little too heavy. The Fan is designed with strength and efficiency in mind. The duct unit is deigned to snap together to save weight. Ducted fan units can be expensive - this is a great cost saving way to have lots! The main duct component is hollow to allow routing of wires. See below for more model details about this genuine STLhive.com part.

    Fan, 3″ x 2.4″, 4mm Shaft (MT1306)<

    This small Ducted fan is to be used with the following motor (MT-1306): http: // http://www.rctigermotor.com/html/2013/Professional_0912/41.html Use this fan with the STLhive Ducted Fan unit or use this propeller by its self. Suitable for aircraft use (Multirotor, Airplanes and Blimps) but it is probably a little too heavy. The Fan is made with strength in mind. We have designed a duct unit specifically for this fan and a small high-performance motor (shown in renderings). See below for more model details about this genuine STLhive.com part.

    Propeller, 105 x 56, 2mm Shaft (3VDC<

    An attractive/efficient propeller/spinner intended for small projects. This product is based on the Pipistrel  Green Flight Challenge (NASA). This version has 3 highly efficient blades that twist as propeller load increases and decreases pitch angle. The Pipistrel design acts a little like a variable pitch propeller with the simplicity of a fixed-pitch propeller. We have taken liberties here - trying only to capture the spirit of the award winning design. This propeller is designed to fit on small hobby motors to be used as a fan for airboats, hovercraft or blimps. See below for more model details about this genuine STLhive.com part.
