Using a hot knife I cut a slot to let the duct assembly clear the tensioner mechanism. ...It ain't pretty but it works<img class="image_resized" style="width:100%;"...

For example, the overhang on the Back part is a functional part of the closing mechanism. The triangular parts of the Front need to press against there when closed for a good fit, and of course the cartridge connection point needs to be spot on. I...

This is simply an extender to allow it top snap in with the existing x axis carriage mechanism. 2 - ShortenedGear.stl - replaces the gear on the x and y axes since the motor is higher than normal. 1 - LcdHolder.stl - replaces the lcd holder...

This file is called 'Gear2_With_Removable_Ring_13mm_with_Extra_Ring_Support_v2.stl" which adds (24) small cylinders over the tips of the 24 gear teeth that are only about one layer tall for a better mechanical connection between gear2 and the...

There is no need to cut anything, from the bottom of the cake tray cover unless the locking mechanism leftovers prevent it from being inserted into the food dehydrator. It does not need and must not be air tight. If you also want to use the dryer...

This is my take on that vintage toy, but purely mechanical – it's powered off the back wheel of your bike. &nbsp;Now, I know noise-making toys are a tough sell with parents, which is why this is the ideal toy for <i><strong>grandparents...

This set starts at 608 as the biggest size, which is pretty much the most commonly used size in DIY projects (filament guides, spool holders, fidget spinners, RC cars, robots, perpetua mobilia...), and goes down to 685, which I use in mechanical...

Screw in the 3 screws to hold it tight. Lower the P2/P3 assembly onto the P1 part, making sure to fold the ribbon cable so it rests neatly above the PCB, not being pinched under any parts Screw the remaining 6 screws into the base, making sure its...

By 1927 computing began to tickle his fancy and he built a differential analyzer, or a mechanical computer to do all the maths! He would teach at MIT penning texts on circuit design and his work would influence the great Claude Shannon and his...

These are all the mechanical parts to build a superlight version of a popular design for a compact tri-band endfed antenna for 40, 20, and 10 meters with a loading coil. The antenna is basically the same design as described by VK3YY at...

Tails is a two-tailed fox, hence the nickname.He is a mechanical genius and skilled pilot. He can fly by spinning his tails like a helicopter rotor and can be seen flying in multiple games and TV shows.Two parts require supports and special printing...

The main difference is that mine doesn't have the same pretty slide mechanism where you can see the shaft of the Head go all the way in. This just gives up too much strength and adds complexity to the print so I just enclosed it. The hardest part...

To later remove the lens, you shouldn't need to pull the locking pin all the way out, but merely a couple of mm to rotationally release the lens. This adapter does not have any aperture-control mechanism, so you can only control the aperture on...

......The essential puzzle mechanism is the same, though Nova has an especially striking appearance: mathematically, the assembled Sirius has the shape of the first stellation of the rhombic dodecahedron, while Nova has the shape of the second stellation.

More details about the build and internal mechanics will be revealed in the coming weeks, but with these files, you can already start building your own 1 meter long OpenRC F1 car remix. We used colorFabb copolyster filament for all parts, each...

I designed this replacement part for the latch on Sterilite TouchTop garbage cans to be as faithful to the original as I was able to, both mechanically and aesthetically. See photos, which show the printed part next to the original, for...

The screw also adds mechanical stability on the lower part. After locking, just add the pulley with an M5x20. Print this one with the slot open to the top. .) Prusa-i3Mk2-y-Beltholder-10mmBelt This one consists of two parts "Beltholder1" and...

It can be printed entirely in PLA but we prefer to do the extruder and X-axis parts in ABS.\nHow I Designed This\nThis design uses many of the same spacing and remixes parts from the Printrbot Play...

The photos show a frame from an IBM Selectric typewriter being bored to suit a larger mechanism, after careful concentric alignment to the existing hole. I used cutting fluid to start with but found it easier to spray a tiny squirt of WD40 on whilst...

The hand crank, when turned causes the center carriage mechanism to rotate around a stationary cone. The motion of the carriage in combination with the stationary cone causes the winding spindle to rotate about its axis. The winding spindle completes...

If this does not work then I will need to extend the housing and seporate the two mechanical functions.The encoder can be redesigned to either:&nbsp;Use reflective phototransistor rather than a break beam style phototransistor, this sholud make that...

For instance, to use the resistor measurement mechanism, you put your probes into the 'eyes' at the front of the stand and the needles sit inside some tiny holes on the back wall to hold them still, therefore if you are concerned about compromising...
