Makertum MK1 230/110 V~ 3D Printer Heated Bed Kits now available

Makertum MK1 PCB (top side, preproduction version)

The Makertum MK1 kits from the pre-production are now available on Tindie and in the Makertum shop starting at €37 or $41, which includes free wordwide1 shipping. Just like in the beta-testing phase, the heated bed comes as a full-kit that contains all the parts necessary to get you up and running. The SSR is optional, just in case you already have one.

Hello Hackaday!

Bildschirmfoto 2016-04-29 um 15.39.07

Between 2011 and now, I spent a lot of time with my favourite startups and companies in northern Germany, building amazing products, pushing the limits of IoT, wearables and 3D printing. In all those years, I’ve always been a huge fan and reader of the blog and the community around it. Hackaday never settled, growing its own virtual workshop,, to gigant crucible in which now the primeval soup for hardware, innovation and makering is cooked. I felt very honored to hear from Mike Szczyz, that they’re considering me as a new member in the contributors column of Hackaday. To make things short: Hello Hackaday, I’m in! See you on the other site!

Interlocking, non-planar layer FDM

Interlocking, non-planar layer FDM (layer highlighted)

A project I’m pursuing since a while now. The idea is to use interlocking, non-planar layers to turn layer tension stress (=weakness of FDM) into layer shearing and compression stress (strength of FDM). Since localmotors seems to be looking for a way to generate stronger parts, I ran the Strati through the gcode postprocessor I’ve been writing a few years ago to demonstrate the technique.

Wipe & Prime Towers for Slic3r


Printing with dual extruders can be somewhat of a tedious task. Fortunately or unfortunately, there are many different aproaches all aiming to easing up dual extrusion or multicolor or multimaterial printing. I tried almost all of the half assed solutions out there, but ended up writing my own gcode post processor, here it is.

UnternehmerTUM MakerSpace GmbH versus Makercommunity [UPDATE 5]


On April, 30. I received the following tweet:

Hey @TU_Muenchen, why is your start-up center trying to register “Maker Space” as trademark?

originally by Peter:

Oh, oh, startup-center, shame on TU!

Socket for the ESP8266 module

2015-04-24 13.35.52

This article covers a socket for the very famous ESP-8266 module, in particular the ESP-07, since a breadboard friendly socket might come in really handy, wouldn’t it? Yes, y not somebody make a really nice one?

The socket should hold a ESP-07 module, whereas the module’s of course supposed to snap in and out easily. Springy contact pins were supposed to make contact to the half moon solderpads of the module. So I sat down to OpenSCAD and build the following:


This tray should then be completed by some 0.5 mm wire..


..where the contact pins would be springy movable in the long holes at the bottom of the socket. To avoid short circuits between the springy movable pins and the pcb traces underneath, I addes some spacers:



The spacers can be used to offset the socket from the PCB.

That’s where 3d printing comes in: It prints out fine with a 0.4 mm nozzle, even though the fine details suggest a finer nozzle.

After some iterations I got the fit just perfect.

Snap in the module into the programmer, flash it, snap it out from the programmer, snap it into your application. That’s it.

Use it for your applications, it’s OpenSCAD source and STL files can be found on GitHub.
