simple engineering 3d models

...and is simple to switch out. but to be fair this model is more made to be full auto. unless you like to have the experience of having a open bolt semi auto. but the FGC-6 H and BL are nicer to shoot on semi auto.this kit comes with a lot of options!

The only difference between the 3 model files is this depth.I printed it without supports, but was really wondering if my Prusa Mini can bridge the part you can see in the 3rd picture, since it bridges around a small corner.It had no problem with the...

voltage (see below)How to choose the right Ballast resistor for the LEDIf you buy recommended LED from the BOM, parameters for formula are: V_LED (forward voltage) = 2.5 VI_LED (forward current) = 20 mA.Example: When your Source Voltage has...

This is a simple print, but does require high accuracy. I recommend you use something like this https://www.thingiverse.com/thing:1622868 to check for over/under extrusion. • To assemble: Place the lids in their open position. Align the lowest gear...

If you have to buy one, I'd suggest a Noctua NF-A9 5V PWM so you can let the board control it.Software (if you're interested)I wanted to use ZFS if possible, to sync snapshots from my TrueNAS box instead of using simple rsync. I also wanted an easy...

A simple rotation of the lamps' cover allows you to turn it on and off. I've printed mine in silver PETG apart form the cover which is done in translucent PETG.You will need:printed cover, base and lid5x M2x4 mm screws or someting simillar and...

The process is simple:Download the STL files and print them out! You are going to need to print:<ol><li>1 x Lilypad Cap, the prime piece of real estate that all the frogs want control of. Looks best if you print it in green filament, but you do...

I achieved this by replacing the clamp mechanism by using a simple closed guide for the 8mm rod and a self tapping screw to prevent rotation and other movement. Requirements: 2 2x10mm self tapping screws (to mount the end-stop itself) 1 3x5mm self...

The goal looks simple, and it's always the same: assemble six puzzle pieces into the interlocking configuration shown in the second photo... But the challenges vary widely in difficulty, from fairly easy to quite hard, depending on which set of six...

&nbsp; If you need to remove the barrel for any reason you can simple back off the front screw and the barrel assembly should be removable.You can use a couple of disc magnets to secure the power cell in place. ...&nbsp;Glue one in the recess on top of...

The circuit is pretty simple, but I'm no expert. Leave a bit of length on the wire so you have room to flip the shell to the side.Connect Battery(+) to switch1 then Switch2 to Meter(+) and USB(+).Connect Battery(-) and Meter(-) to USB(-).8) Once...

In order to keep the assembly of mirrors as simple as possible, a system has been designed to fold as few times as possible (to reduce the increase in the number of actuators and implicitly to reduce the complexity of the model). The ability of...

To orientate the inflatable structure a bevel gear design would be used around the vertical axis and a simple pinion gear design for the horizontal axis, which would be covered by MLI attached to the back of the moving solar/ inflatable support...

Thank you very much and happy printing!&nbsp;AssemblyNo hustle in assembly, just three steps and you are good to go:Print it;Insert the Raspberry Pi;Snap fit all together.Simple as eating a sandwich ;-)No fan neededThe case is designed to optimize...

This is a hanging mount for the Original MMU2(s) Filament Buffer. [PC4-M10 Version] Features: Quick &amp; Easy to load Reuses most of the original parts Keeps the Buffer out of the way Clean simple filament path to the MMU2(s) (Prevents MMU...

All necessary labels have been provided, making further adjustments extremely simple. Another set features same size - eight-tooth with diameter at roughly five-eighth inches and outside measurements about sixteenths or fifty four-hundredth more. ...

This is a variation of that, which works really well as a stand-alone simple machine for winding up those 35mm films. There are a variety of applications/uses for this as a sand-alone piece, which is why I'm offering it to the world.</p><p>To see...

SolidPython is a python library that lets you create your models in python (using proper variables, loops, etc), and it generates simple SCAD for you. Get SolidPython from here: https://github.com/SolidCode/SolidPython You can simply copy...

The Y endstop mount fits on the bed rods, while the front-adjustable Z endstop mount is fitted to the frame and Z rod. This is my first use of a simple concept, to mount parts on the printer using clips that span two rigid points, either from the...

After trying to find an electronics box to house both the Ender Melzi board and a Raspberry Pi for an Ender Extender, I couldnt find one that I liked so I made my own. The box fits under the bed and in the gap where the electronics once were housed....

#Gemst ne JEWELLERY # #Solitaire Jewellery is for those who appreciate simple yet elegant designs. ...Our CAD files are a perfect blend of classic sophistication and timeless charm, with stunning gemstone rings, earrings, pendants, bangals,...

The secondary goal was to keep it simple and quick to print.The tripod consists of the following components:Tripod Head: Featuring fixed holes positioned at 20 degrees from the central axis.Telescopic Legs: Made from 6mm outer diameter and 4mm inner...

The bottom, a simple plain with rounded edges, the shell which has a one perimeter thick wall that acts as a support for the top that slides on the Ikea Lack's leg and a core that is the shape for the gyroid and has an offset of one perimeter from...

Some people are concerned that because the virus is so much smaller that 0.3 um that they think it's like, "trying to stop grains of sand with a chain link fence" but the physics of filtration is not that simple. Here's a good paper on what size...

&nbsp;See pictures attached.Both flow volume and flow velocity appear to split evening between the left and right ducts!&nbsp;Note: The max flow velocities are a bit artificial, since I just used a simple 4.4CFM as volumetric flow input. &nbsp;The...

These better illustrate the differences in the three materials than the simple details given above. Cast Metal.stl Post-Print Details This print was less than ideal, but I was still able to learn quite a bit from it. I printed it as the STL appears...

Plus I know how it works so if it breaks I can fix it. The winders function is pretty simple but really fun to watch. The motion of the winder can be explained as such. The hand crank, when turned causes the center carriage mechanism to rotate around...

This started out as a simple Laser pointer for my wife, but since I couldn't leave well enough alone, it has turned into much more. First off, I need to give credit to TheDoctorsApprentice for the inspiration with...

The chain mount is a simple open box with two mounting points for frame clamps. This specific version is made to fit an ABUS 64TI/50HB80 padlock and a 6KS85 chain and the attachment clamps fit a 31 mm round frame. STEP files are available for those...

This project started to solve some problems I had with this dock from Hackaday, and I ended up totally redesigning it.Here's a list of this dock's major features:It makes contact using pogo pins, which are simple to install and reliable.The wiring is...
