MSA Phalanx to 40MM NATO (RD40x1/7) Adapter ======================================== This prototype design for a MSA Phalanx non-disposable respirator to 40MM NATO (RD40x1/7”) gas mask thread adapter, as requested by dclaw. Designed to help cross...

After testing three prototypes, here's what I've learned: the three versions take approximately 30 minutes to print. Version 1 created a great seal but was slightly tight around the nose and needed improved attachment points (too close to eyes). ...The...

The STL files provided by MSA still contained prototype features that weren't necessary, parts that weren't required by my version, and areas that could be improved to enhance airflow or facilitate eyeglasses. I utilized Tinkercad to modify/create...

I have made prototypes out of PLA and ABS but I am using ASA for the final version as it has better weather and temperature resistance. Be aware that they will get hot under heavy braking so PLA and PETG might not be suitable. I haven't tried...

The wires for the contact pads then have to be connected to the touchpads which I printed and conductive the prototype is shown above is My first Assembly and I have modified some smaller pieces on it to make it go together better the installation of...

small prototype board for two x 74HC165. This may not be necessary if you have access to a premade PCB. For Diode matrix version: 16 x 1N914/1N4148 etc. small signal diodes. 1 x 2m micro USB cable. Circuit schematic included for...

On a prototyping board I have a 7805 regulator for the 5 volt rail. The motor can run on 5V or 9-12 volts on the power supply. Use 1k resistors between the arduino PWM pinouts and the base of the NPN transistors. These power the 16 or so UV LED's. I...

This prototype design enables a 40MM NATO (RD40x1/7") gas mask thread to connect with Dräger X-plore® 3000/5000 series filter cartridges. The adapter's unique feature is the ability to clock the position of the bayonet/cartridge separate from the...

I know from doing several prototypes that if the button tab is a bit loose, a drop of super glue will hold it in without damaging the drive. I recommend assembling it in this order: 1. Attach the button first - see the picture above to see how a...

Will Prototype When My Whit Filament Gets Here. Try It If You Like. 4/12/2018. I Added LED Light Bars That Can Be Added to the Existing X Axis Wire Bracket to Install LEDs Just Below the Z Rail. Those Additions Will Fit the Tevo Michelngelo and the...

Timeline: The development and deployment of the new ladder system is expected to take several years, with the following milestones: * 2024: Initial prototype testing and evaluation * 2025: Full-scale production and deployment of the new ladders *...

The first British prototype flew in 1933 and was subsequently designated Avro Cierva C.30 Rota Mk 1A. These Rotas were employed by the Royal Air Force (RAF) for calibrating its fledgling radar network prior to the start of the Battle of Britain. One...

To evaluate its prototype-making abilities, generally using this will be enough, Even so these specific values used depend greatly upon individual CNC printer requirements. These digital file formats are suited to usage with CNC Routers, also as...

After many prototypes and some complete design reversals, here is a functional mechanical calendar solution that can be realized with your 3D printer. The date is incremented by simply pressing the "One More Day" pedal. The month is incremented...

Draeger X-plore Bayonet (3000/5000 Series) to 40MM NATO (RD40x1/7) Adapter This prototype design for a Dräger X-plore 3000/5000 series respirator to 40MM NATO (RD40x1/7”) gas mask thread adapter is designed to help cross compatibility of commercial...

Only a single prototype was built before the Armistice between Italy and the allied armed forces, which ended the project. The P.119 was designed (in 1939), to minimise drag by fitting the engine in mid-fuselage in a similar layout to the P-39...

... 20 lengths of Stainless Steel 170x2.5mm Transmission Round Rod on eBay). With more experience under my belt from building a prototype 3450 Gallon Tender, I've added a variant with steps front and rear, while keeping the stepless version in place...

The box for the electronics has two slots for prototype PCB boards (30x70mm) I've used one to mount drivers for status LEDs and a voltage divider for the inductive sensor. STILL in Progress are; A lid for the box (probably will print in clear). LCD...

I made several different prototypes and this SANDBOX 2.3 works best for several types of elements and reflex tube lengths. The full range element makes this speaker easy to assembly and no soldering is needed. The 2 kg sand inside the SANDBOX 2.3...

This is a prototype face shield that Andrew Hong and I have been working on over the past couple of weeks. Before I get started, I need to thank Gina and Laura for being heroes on the front line and providing us with crucial feedback on our designs.

Sundstrom SR Series Filter (SR100/200/900) to 40MM NATO (RD40x1/7) Adapter This prototype design is for a Sundström SR series respirator (SR100/200/900) to 40MM NATO (RD40x1/7”) gas mask thread adapter. The goal is to facilitate compatibility between...

This is My Second Prototype for Aligning COSPLAY Armor and Other Structural Builds. Problem: With large armor pieces that needed to be cut into multiple sections, either for fitting on a human or due to small printer sizes, I discovered that velcro...

Honeywell Safety Sperian / Survivair ValuAir Respirator (Bayonet) to 40MM NATO (RD40x1/7) Adapter This design is a prototype for a legacy Honeywell Safety Sperian / Survivair ValuAir bayonet non-disposable respirator adapter to 40MM NATO (RD40x1/7")...

In my prototype case, I used a 40mm fan with integrated blue LEDs. In the second case, I used a silenced 40mm fan and two pieces of LED strip glued beside the fan. Both versions look cool. The power switch can be found on Reichelt's website. You...

Note: The Z part you see is my first prototype, which I had to print in two parts and join with epoxy due to underextrusion on one layer. I decided to save resources and leave it in place. The final part uploaded here is debugged and optimized but...

Scott 742 Series, Promask 25, Xcel, and Scott Quarter Turn Bayonet to 40MM NATO (RD40x1/7) Adapter This prototype design for a Scott 742 Series, Promask 25, Xcel, and Scott Quarter Turn bayonet non-disposable respirator to 40MM NATO (RD40x1/7") gas...

As of 08/05/2020 I have not personally tested the presets as my print queue is stacked, however they are built from previous prototypes. Testers are much appreciated. *If you like this design, please consider donating through the blue "Tip Designer"...
