Strange walls/faces when importing self made model from Blender to Cura 3

I wanted to create a coin stacking device similar to this one: https://www.thingiverse.com/thing:499177 But I wanted to only 3 coins, 5c, 2c, and 1c. Unfortunately the STL came in pretty messy after importing to Blender, which made it difficult to…

Does PETG fade in the sun?

I'm looking at scanning in a statue on my pond and making a print of it. I'm wondering if PETG will fade and how fast. I'm thinking of using white or maybe a bone color if possible. If PETG fades kinda fast, what material should I use? Keep in mind…

How to avoid collisions with already printed objects?

When printing several objects, I recently encountered a problem that arises when the structure in itself is relatively thin or the support towers have a small surface: the printhead would in motion tend to knock one or more over as it traveled or…

What is the best method of printing joints for action figures?

I'm interested in 3D printing toy action figures, but what I don't quite know how the joints should be designed to allow flexibility. I could imagine maybe something like a screw and nut for the arms and legs that are separated with a hole in the…

Bowden tube clog

There's PLA filament clogged in my Bowden tube, is there a best practice for cleaning it out or do I need to replace the whole tube? Also, the couplings are totally stuck, so I guess those would need replacement too or are there ways to get stuck…

Route to transform 2d image (depth map) into a curved bracelet (and STL file)?

I've got a bracelet concept that I've sketched up as a flat design. I'm trying to found a route by which I can extrude this into a 3d object (depth map?), curve it into a bracelet, then ultimately create a STL file out of it. I'm having trouble…

Laser cutting on RepRap

I have seen some lasers attached to the RepRap platform for cutting but most seem to be cutting paper, balsa wood, or merely etching. If I were wanting to build a platform for cutting wood, similar to the wood framed or boxed 3D printers on the…

Sudden underextrusion on Ender3

I have printed a couple weeks perfectly fine with my Ender 3. Two weeks ago I changed the firmware but the settings were all fine and resulted in good prints. Now, suddenly during a print the extruder motor started to under-extrude. I thought "hey,…
