Buyers Beware - Shady Banggood Shipping Cost Settings

Just a quick heads-up - I ran into some "issue" with the Banggood web shop system that sneakily introduces shipping and insurance costs even if you select "free shipping". There's an option for that, but the option keeps changing for some unclear reason - if you're not careful, you end up paying for shipping and handling that you didn't consciously select.

This is a re-recorded version of my presentation given at the SAP Inside Track Berlin on September 2nd 2017. Apparently, there were some kind of audio issues during two of the sessions, one of them being mine - so instead of simply dropping the slides off somewhere and leaving you with an incomplete presentation, here is a recording of the slides with voiceover. 

Deltonator Build #5 - Small Steps #1

In this fifth video I mount the LCD touch screen and add a layer of insulation beneath the heated bed. Little progress, but progress nonetheless...

Deltonator Build #4 - Bed & Bunny

In this fourth video of my 3D Delta Printer build project, I mount the bed, fix the arm joints, add the bed height sensor and perform yet another test run.

Cable Management System Clone

This is a rough clone of the wire management system designed by Ivan Miranda using Fusion 360 in his video - cloned by request, one might say. 

Deltonator Build #3 - Arm-y Issue

In this third video documentation of my 3D Delta Printer project, I assemble the arms, mount a temporary effector placeholder and check for effector tilt.

Deltonator Build #2 - The Three Towers

This is the second video of my Delta 3D printer assembly in which I assemble the frame and give it a first test run.

Deltonator Build #1 - Part-y Preparations

I'm building a Delta 3D Printer (yep, yet another design) based on MakerSlide vertical rails. In this video I prepare the printed parts and pre-assemble some of the components. The entire design is open source and can be found at

HEJLILL - Werkbank für < 150 €

For the past few years, I’ve used a metal storage rack as a makeshift work area. It never was a satisfactory solution, and for some of the upcoming projects I definitely needed something with both more stability and a bigger (and level!) working area. Professional workbenches are way too expensive and wouldn’t fit into my basement anyway, and much of the hobbyist stuff sold on the internet or at hardware stores is not much better than the wobbly racks I threw out. Hence, I decided to build my own workbench from stock parts that you can get from IKEA and/or a hardware store.

Let there be light...

I recently bought a 3D printer. I'm not sure yet how much use it will actually see, so I went for a cheap model - one of the usual acrylic DIY kits shipped from the far east. While it's actually working rather well, there are a few details that are bothering me. For one thing - you can't see what's going on beneath the nozzle without a torch. However, using a 3D printer and some LEDs, resistors and some experimental circuit board, that problem was easily solved...
