In this example, rectangle0.333 - the 'height' of the thread is one-third of its 'width.' In addition, the pitch is 8 mm while the thread size is 6 mm, and groove is set to true. openscad screw threads with linearextrude by speedymollusc - Thingiverse Download files and build them with your 3D printer, laser cutter, or CNC. The screws/bolts, black mount with boss have printed threads as does the large Bolt/Nut. Specifies a 'square' thread that is actually a rectangle. The square with center boss: Has two outer shell and the boss has 6 inner and 6 outer shells for cutting threads with a real Tap. They are printed at the same time (as two parts in their correct location in '3-D space'. Some dialing-in of Shells and Density is needed but, if planning on ‘Chasing’ the threads with Tap/Die, then I make that element of the part as a separate design and print with two processes (no point in printing aspects not needed on other features). If holding strength is needed, I can accomplish this by one of two way’s (or a combination of them): Increasing the number of Shells and/or Post-Processing with a real Thread-Tap or Thread-Die to ‘chase’ the threads. PETg has some problems but, can also be dialed-in for a useful part.ģ. The print-process parameters can be dialed-in to get ‘good enough’ parts, especially using ABS and PLA. Optionally, the parts can be scaled up/down to compensate for the (common) 2% shrink (generally on the part with the internal thread).Ģ. module augerthread (outerdiam, innerdiam, height, pitch, toothangle30, tolerance0. The fit between mated parts of compatible threads also depends on Shrink and without some thread ‘chasing’ binding can occur. module screwthread (outerdiam, height, pitch0, toothangle30, tolerance0.4, tipheight0, toothheight0, tipminfract0) // this creates a vertical rod at the origin with external auger-style // threads.

The resulting threads (for me) have always been good enough to mate with intended part (nuts, bosses, etc…). Screw threads Snap ins Gears Hollowed objects If you can handle those projects, you’re probably now skilled enough to handle almost anything in OpenSCAD. I can easily print 3/8-16 Bolts, Nuts and threaded Bosses, as shown below.ġ.

I’ve printed many parts with threads and have made several observations about doing it. You can also open it in customizer to obtain a screw and / or nut thread of the desired size that you can include in your own designs.
