Description
This is a remix of toto_28's Fidget "Gear Keychain" https://www.thingiverse.com/toto_28/designs please visit his plane collection toto_28's design has great features: * Solid Shell * Effective gears designed to spin and not pinch * NO HARDWARE required to be purchased to assemble it. * Loop for optional Key chain or cord To print the remix with the ORIGINAL shell design you need the included Remix_ toto_28 _Fidget_box_rivets_version.stl and from toto_28's original post https://www.thingiverse.com/thing:4621056 the gear wheel file "wheel.stl" Be sure to print two., or I have now included it as file toto_28_Fidget_remix_1x_wheel_original.stl My remix is all toto_28's design except for the center shaft. I made it a solid center shaft to hold the gear and a washer to be held on with a 1.75mm filament rivet. The changes ensure what should 100% success on assembly and the wheel spins more freely. So what is a filament rivet. I was introduced to filament riveting in the "Articulated finger extensions" project by JulienJeanRoy https://www.thingiverse.com/thing:4342323 You use a soldering iron or wood working tool, set to the lowest temperature, and melt the end of a piece of filament down to a mushroom. Do one side, insert it into your work. Trim the other side so about the thickness of a piece of filament is sticking out the other side... and then melt that side down to. NEW OPTIONS Pick a BOX of the size you want to print and a WHEEL. All the other files are spare parts or different options. I printed a 2X version. It printed OK, but with 2X size comes 2X tolerances. The spacing inside the box increase so little fingers could get between the gears. The Scaled versions take out some of the design grace by wrapping the cage around the gears more. You can print 1x, 2x, 3x and 4x which I have not printed myself. If you want a custom size, let me know as it is code generated. 2x and above will print with center pins since filament will no longer work. 2x gives you a wheel option with "finger protection" which fills the gear openings to make them smaller. 3x and 4x I only offer that version, but you can always regenerate the original at the scale you are printing if you prefer that. EDGE CUT VERSION There is now a version in each BOX size that prints with one wheel exposed out the side. This allows for thumb or other finger roll action. ** YOU NEED TO SUPPORT THE cutout ** Tolerances are close so be sure to remove all support material. PRINTING .4 nozzle, .2 layer height is fine The washers are tiny. make sure they bond to you bed properly. Assembly: Print Remix_ toto_28 _Fidget_box_rivets_version.stl which will print two washers of the BOX color. If you want different color washers you can print those with "Remix_toto_28_Fidget_Optional_Separate_washer_with_inset.stl" Print two wheels from toto_28's original post. Put the wheels on the BOX with the recessed side up. For SIDE CUT positions, insert the wheel into the cut first, align it with the PIN and let it settle down. It can be removed, turning it while lifting it off the pin helps. Melt one end of a piece of filament, put it through the hole on the bottom of the box at the Y Put the washer on recessed side up Cut the filament to a length that is a little bit more than the thickness of the filament. Melt it down onto the washer... don't hold it there. Once it is down remove he heat. NO NEED TO PRESS HARD> These are a great party gift. Do remember they do have little parts should they come apart so distribute them wisely.
