Spinner with two magnetized rotary knobs and a very satisfying ratchet mechanism.
External Hardware:
1x countersunk screw M2.5x12mm
1x countersunk screw M2.5x20mm
2x M2.5 x 4mm brass heatinsert
2x 608 bearing
14x D6x3mm magnets
Assembly:
Heat Inserts: Press the M2.5x4mm brass heat inserts with an soldering iron into the clickspiral on both sides. Make sure that they are straight and flush with the top and bottom.
Clickmechanism: install the clickspiral into the clickroller. Be aware that there is only one right direction for it to fit in. If it is installed the wrong way the click operation might suffer.
Clean bearings: To make sure the operation of the spinning part is smooth, give the 608 bearings a good wash in isopropyl alcohol to get rid of all the grease inside. To protect them from rust you can also use WD40 afterwards
Bearing assembly Press the Bearing into the knob and make sure that the bearing is flush with the top. Repeat this for the other knob aswell.
Magnets: Install the magnets into the knob. Make sure that the polarity is always the same. Repeat this for the other knob as well with the opposite polarity (the thwo knobs should attract each other). The magnets should friction hold, but if yours are too lose you can secure them with some ca glue.
Screws Insert the distance piece into one knob and the clickmechanism into the other knob. Now you can screw the two sides together. When tightening the screws use two allenkeys on both sides and dont grab onto the ratchetwheel (it could break).
Have fun
Operations:
Spinner You can hold the fidget toy onto the fastener pieces, the clickroller or place it onto a flat surface and spin both knobs simultaniosly.
Knob operation You can turn each knob against each other and they should snap in 51,4285714285° degree steps into place.
Ratchet / clickmechanism You can hold the fastener pieces and turn the clickroller in one direction. It should make a satisfying click on every increment.
Vibrating If you hold onto the fastener pieces and turn the two knobs against each other it starts vibrating.
