Thrustmaster HOTAS chair clamp adaptor

thingiverse

A pair of adaptors for allowing ratchet clamps to be used to mount the popular Thrustmaster Hotas One, T.Flight Hotas 4, T.Flight Hotas X and T.Flight Stick to an office chair with arms. Ratchet clamps with soft jaws (as below) should conform to most chair arms, but please do check before printing. Also check the interconnecting cable between the 2 HOTAS units will be long enough to reach between the arms and still allow you to sit down! The adaptor comes in 2 parts with a keyed socket that allows the joystick to be rotated for comfort in the horizontal axis in 2.5 degree increments. The part that attaches to the HOTAS should be printed with 100% infill neither part requires supports for printing. I have been using these for over a year on 3 different office chairs, having racked up 6000+ hours in Elite without issue. Requires 8 x M6x 20-25mm large headed (15mm dia or large washers) machine screws and 4 M6 nuts to match. An additional 4 nuts may be required for some variants of the HOTAS, which do not have the captive nuts fitted into the base, these can be easily added to the HOTAS if required with minor dis-assembly of the HOTAS. Print 2x Joystick adaptors, and one of each of the clamp adaptors (which are mirrors of each other). Ratchet clamps, these are very cheap and have a 6mm hole drilled at the end, which allows the adaptors to be firmly attached. They also come with soft jaw covers to prevent damage to the clamped item and provide a firm grip. https://www.amazon.co.uk/gp/product/B0875TD935 Other clamps with a 13mm wide x 4mm thick bar may also work.
