20x 1/4-20 Brass Threaded Heat Set Inserts for Plastic 3D Printing Brass Metal
Product Description
Pack of 20 threaded inserts.
These create much more convenient and professional parts than using "captive nuts" (where you have to design a slot for a nut, and then place the nut in the slot and hold it there while affixing a screw). They also can be used in some situations where captive nuts just don't work.
These are inserted into a hole in the print that is slightly smaller than the insert, and set in place using a soldering iron to melt the plastic around the insert. The inserts have a slight taper and small fins that the plastic flows around, resulting in an extremely strong bond.
Rather than adjust designs around the limitations of 3D printing (supports, print bed size, etc), divide your parts into separate components that fasten using these inserts and machine screws. Not only does this give you greater flexibility when designing a part, but also allows you to re-print only failed components rather than full assemblies - saving time and money.
These are threaded 1/4-20, which is the correct size for most camera tripods
This is the shorter of the two sizes of 1/4-20 inserts we offer.
The height / OAL is 0.3" and the *approximate* recommended hole size is 0.363" tapering to 0.349".
The depth should be approximately 0.030" greater than the OAL of the insert.
Due to a number of factors (3D printer calibration, material, temperature, etc), the optimal hole size
for your application may be different. This should be a good starting point for you to find the best values for your use via experimentation.
