Don't be a **** and try to sell these to hospitals or people in need. They cost pennies to make. Made the top flat so you can print in stacks. Centered and extended the cut. The Fullcut version removes additional material along the strap while still maintaining some rigidity.

No Idea cg Tech designed the first one. I just redesigned it to better secure it to the motor, mine kept vibrating loose. Mount for small fan to air cool the extruder motor when printing PLA. Arrows need to point to the back. you wiggle the part on from the Y plane don't try inserting from the Z plane or you will break the part. Stretch the sides slightly when pushing the front on top of the extruder motor to finish installing. You should hear a click once the part is in place. The triangles on...

There is one solid layer covering the screw holes. Insert nuts then insert screws to tighten. For inserting phone press down on the top section and insert. The neck should be flexible enough to give enough clearance. To remove press down and remove phone.

Gaseous oxygen and hydrogen propellants used in a special engine energy cycle called Full-Flow Staged Combustion are believed to significantly increase the lifetime of a rocket engine's pumps. The cycle can also reduce the operating temperatures of the engine. Improving the lifetime of the hardware reduces its overall maintenance and operations costs, and is critical to reducing costs for the joint NASA/industry Reusable Launch Vehicle (RLV). The work in this project will demonstrate the...

A heat shield for thermally insulating the leading edge of a wing of a spacecraft during ascent and reentry includes a plurality of rigid tiles. Each tile is formed with a pie-shaped element which interlocks with the complementarily-formed element of another tile. The combination of structure afforded by the pie-shaped elements substantially impedes hypersonic flow of any gases that might enter the gaps between tiles.

This report spans activities covering approximately 13 years. This period includes both the TSS1 and 1R missions. As is well known the TSS1 mission was not successful due to the tether hanging in the reelout mechanism. This resulted in the approval of a reflight mission. TSS1-R. The reel mechanism did work on the reflight however the tether arced, burned through and flew away just as maximum length was being obtained. Thus only a few of the planned objectives were carried out. The good news is...

In early 1958, when the Soviet Union and the U.S. had each launched two satellites, it was obvious, from comparing their weights, that the Soviets were using much more powerful launch vehicles. This led to great concern in the U.S. about the apparent lag in vehicle capability. This concern was not entirely justified when all the technological gains associated with the development of intercontinental and intermediate range ballistic missiles were considered. Modifications of these vehicles...

For several years, NASA's plans for Mars exploration have included a 1979 Viking Mission as a logical follow-on to the 1975 Viking Mission. Future budget estimates are not firm though, and they may allow resources for Mars exploration which will not be sufficient for an ambitious and expensive mission such as Viking. Rather than abandoning Mars exploration until some time when budgets are more favorable, NASA would like the option to continue by flying more modest missions. One such option...

Given many assumptions concerning cost, it appears difficult to deliver oxygen to LEO for less than the projected delivery cost of a large Shuttle derived vehicle (SDV). The...

These dies are bonded at specific sites on a glass, prepatterned substrate. Thermal data is multiplexed and recorded on each individual pressure measuring diaphragm. The device functions in a cryogenic environment without the need of heaters to keep the sensor at constant temperatures.

Tropical rain systems, such as hurricanes, typhoons, and monsoons, are crucial to sustaining the livelihoods of those living in the tropics. Excess rainfall can cause floods and great property and crop damage, whereas too little rainfall can cause drought and crop failure. The latent heat release during the process of precipitation is a major source of energy that drives the atmospheric circulation. This...

Running resistance, the combined resistance induced by aerodynamic drag and mechanical friction, absorbs about 16 percent of railroad budget and maintenance costs. In order to study these losses, AT&SF Railroad entered into a joint research project with the Jet Propulsion Laboratory. Various train configurations were tested when the resulting data was computer analyzed. The Coast-Down Technique was estimated at one percent accuracy. AT&SF is evaluating the data further.
