OpenSCAD can't render union of two polyhedrons, but can preview just fine

I am running into what honestly seems like a bug in OpenSCAD, but I can't believe that something so simple could reveal a bug. I am trying to render the following code: module tri_prism(base1, base2) { polyhedron([ base1[0], base1[1],…

I've been trying to do some research on Linear Advance (LA) on Marlin and Pressure Advance (PA) on Klipper, and from my understanding the technology behind each is different, although also similar. If I understand what I have read correctly,…

Good filament/s for heat resistance in cars

I have designed a cupholder for my center console in my truck with PETG. I was hoping it wouldn't deform and it didn't for a while but we got some high temperatures the past few days (around 32-38 °C or 90-100 °F). Kind of figured it wouldn't hold…

Can I print my own Lego bricks?

Assuming I've 3D design (or I've created one) which looks very similar to Lego bricks, I am allowed to 3D print them for my personal use? Do I need to obtain some permission to do so, because of some patents? Or how does it work?

How to get less Z-seam?

I printed this Curvy vase from Thingiverse and it came out pretty well on my Chiron. However, I am not happy with the Z-seam that is very large. When I look at other people's problems with this, they often seem to have too little filament at the…

Do I have to buy all new components if I were to get a RAMPS 1.4 that supports 24 V power?

Ryan Carlyle seems to keep suggesting in my questions here, that using a 24 V power supply is safer than using a 12 V one. Early on, I ordered the wrong power supply, obtaining a 24 V one instead of a 12 V; I found that it was incompatible with my…
