I designed a set of 10 Christmas ornaments that can be 3D printed in vase mode for Printables’ Winter Holidays Decorations contest.

I knew when I started my design process that I wanted to design something that could be printed in vase mode.

Designing Christmas Ornaments for Vase Mode

I wanted a lab rocker, but (as usual) didn't like existing designs. No, "not designed by me" is not the most critical flaw by itself. But anyway, here's my take on a servo-driven DIY rocker with variable amplitude and frequency. I made it to develop #photoresist and to etch #PCB , but I'll probably use it to develop glass plates of my #largeformat camera at some point.
Geometry of the liquid cobtainer is customizable, as well an many other parameters. 3d-model is written in #OpenSCAD with #BOSL2

My contributions to Printables/Thingiverse are getting increasingly low-effort :D. Like, wtf, hooks, phone stands... What's next, "a rectangular box, untested" or some ugly unprintable AI-generated figurine?
Anyway, I had no choice but to design this thing, since I didn't find any good tweezers, suitable for grabbing a #PCB by the sides out of corrosive solution and holding it very firmly. So I decided to publish it as well.
#OpenSCAD + #BOSL2 as usual, very parametric.

My next contribution will be more substantial. I'm going to publish that #DIY lab rocker visible underneath soon.

Dear #OpenSCAD users: is there any way to define a real #Bezier curve with OpenSCAD ?

My current understanding is that there are functions for some geometric figures (straight lines, circles…) but not for Bezier. #BOSL2 provides Bezier helpers but apparently, they only approximate a curve with 16 straight segments, right ?

Does this mean I should stick to #FreeCAD if I want smooth and parametric Bezier curves ?

I made a chamber heater for my #Voron 0 using an old toolhead with #OpenSCAD and #BOSL2. While it lacks the power of a commercial heater, it maintains a chamber temperature of about 40°C in my garage, which is ideal for printing with PHA, a biodegradable and heat-resistant material!

After adding an auxiliary fan and a servo for a retractable nozzle cleaner, I have run out of available pins on my Fysetc Catalyst v2 board 😅

@matths #BOSL2 is a hell of a drug :D

Yesterday I noticed some suspicious soapy water under my washing machine. The hose that I inserted into weird threaded tube in the wall a year ago slowly creeped out of it.
No idea what the shit this imperial-based abomination is, I measured 33mm thread diameter and 2.3mm thread pitch and found nothing similar in local shops. I couldn't trust the friction anymore, so 3d-printing to the rescue.
#OpenSCAD with #BOSL2 of course.
The geometry is unfortunate enough to require two parts that barely fit together, but after assembly everything is holding tight.

@me Could you use path_text() from #BOSL2? https://github.com/BelfrySCAD/BOSL2/wiki/shapes3d.scad#module-path_text.

@fmn That was quick! I'm still learning, but really like #openscad and I like it even more since I discovered #BOSL2. Here is one way to make the same object using this library:

include <BOSL2/std.scad>
$fn = ($preview ? 45 : 90);

vals=[360, 350, 1.5];
grid_size=[340,340];
hole_r = 2.75;

difference()
{
cuboid(vals, rounding=vals.z, except=BOTTOM, anchor=BOT);
grid_copies(size=grid_size, spacing=[10,10]) down(0.1) cylinder(r=hole_r, h=vals.z+0.2);
}

Not that it makes any practical sense to repair this screwdriver, but it is my first new tool, that I've bought after moving to Germany, I don't want to just throw it away. It was incredibly expensive too, 5.49€, not the price I was used to pay for a screwdriver back then :D.
The rubber part slowly desintegrated during a decade of usage, I recreated and improved it in #OpenSCAD (shoutout to #BOSL2 and to smooth_path() particularly, they make it super easy to reverse engineer fancy curves using only calipers), and 3d-printed with TPU.
