Keyboard stands like to break...

The day before yesterday, my 1.5 liter water bottle fell on my upturned keyboard. It was locked, but the force of the impact alone caused the little stand for raising the keyboard to break, and so the usual keyboard wobble started. Normally this would be the moment you buy a new keyboard because a 2.5cm by 1.5cm by 2mm thick piece of plastic with no moving parts broke. I found that somehow... wasteful of resources. So I fired up my 3d printer ...

You just have to know how to help yourself...

A mishap and "too" floating parquet are a certain problem in times of Corona. I had to take care of the baseboard in a makeshift way, but I was able to do something about the gap caused by the floating parquet: 3d printing makes that possible, too: Both are just makeshift repairs, but for now, it works fine and the tongue and groove system was great to recreate. :)

3d print: happy easter egg

Today I just printed out a bunch of Easter eggs that I hope will be a nice surprise for colleagues (when you’re back in the office sometime). Until then, I’d like to show some, I think quite interesting and successful pictures of the eggs, showing how the layer structures are built up, how something looks like at 300 micrometer layer height in FDM and that, depending on heat and material, sometimes threads form in cavities, which can be ...

Small 3d-print: Headphone (Bluetooth) charging problem helper

I’ve been having problems with my Bluetooth headphones lately, because sometimes they just wouldn’t charge anymore. After a little testing I found out what the problem is: The magnets (at least one of them) in the charging case are not strong enough to attract the earpieces properly. This makes them quite useless, because I would have to press the earpieces by hand or e.g. with adhesive tape into the case and charge them. I have done this ...

Mask with integrated face shield or how to show mouth expression despite corona and the obligation to protect the mouth/nose...

Masks are a helpful tool to prevent the spreading of viruses such as SARS-CoV 2 and should be worn by as many people as possible within the given regulations. Unfortunately, however, they also prevent the perception of the most important facial expressions of people, so that it is currently much more difficult to simply give a smile. The alternative to this are face shields (FaceShields), which actually only help against spitting / direct drip ...

Breathing mask from the 3d printer

A company from Baden-Württemberg called "Cast Solut" has developed a respirator that can be produced by injection moulding and that reduces the use of filter material to about 1/5 of a normal respirator. Well done one can only say. Of course things get even better if you can download the 3d data for it and print it out on your home FDM printer. The 3d model is available on the website - thanks for that :). But when I downloaded it, I noticed ...
