600 Watt, 3d-printed, Halbach Array, Brushless Motor

This is a very powerful, 3d-printed brushless motor. The main components like rotor and stator can be printed with a common FDM-printer. Magnets, copper wire, and ball-bearings are ordinary components available on eBay or AliExpress. The motor is a redesign based on the learnings from the makeSEA Motor. It has 600 Watts, and performs with more than 80% efficiency. The magnets of the rotor are...

Lamer Turbillon

This is a mechanical watch with tourbillon driven by a 3d-printed mainspring. The watch has a Swiss lever escapement. The mainspring inside the going barrel keeps the watch running for approximately 30 Minutes. Accuracy is roughly one Second deviation within one Minute (depending on print-settings).

The project demonstrates that the 3D-printing technology is developing. Compared with...

Machine Vise

This is a quite robust 3d-printable machine vise. It's 100% 3d-printed - no screw or other piece of hardware is needed to hold the individual pieces together. Pieces clip and snap together. It's a demonstration that it is very important to consider forces and material properties already when designing a mechanical object. Hints about proper design are presented in my video: ...

Slew Bearing, Parametric Design with Fusion 360

Ball-bearings are very popular for 3d-printing. However they often fail for real applications. Using Fusion 360 I've created a parametric design of a "Crossed Roller Slew Bearing". The result is a pretty accurate and robust bearing. The bearing including the rollers is 3d-printed in separate parts. There are a few screws needed to clamp the two halves of the inner race together. ...

Ultimaker 2 - Print Head Top Replacement

The top part of the print-head of my Ultimaker 2 did break (probably I over-tightened the thumb-screws). Here is a replacement-part, which I designed with Fusion 360. The slightly different design is probably more robust than the original. I recommend to print it with PETG (or ABS), no supports needed. I have successfully printed it with Makerbot Replicator and Ultimaker.

Un-Lockable Loose Filament Spool

Who doesn't know this problem: Tons of loose filament samples. Without spool, they are tangled up, and you certainly don't (want to) have a spool for each sample. For changing a sample it's needed to un-wind and re-wind the filament ... :-(

With this 3d-printable spool, it's possible to unlock the spool and simply remove the sample.

Oct OClock

  It’s time to rediscover time. In the digital age humans are still analog beings. Oct O'Clock transforms the time into decorative patterns, and leaves it up to you, how exactly to read the time. The Oct O'Clock is mainly designed as a wall decoration, which also shows the time. It’s simple to roughly read the time, and more difficult to read it very accurately. Time becomes an...

About Me

Christoph Laimer


makeSEA Chief 3D Designer

Award winning 3D designer, Christoph is responsible for some of the most innovative designs, observations, and insights available on the makeSEA registry. Hailing from Zurich, Switzerland, a stronghold for master tradesmen and creatives since the 12th century, Christoph couples his formal expertise in electrical engineering and software development with his passion for mechanics to design 3D printable mechanical clocks, motors, and a variety of scalable components and usable objects. He is also a primary contributor to the makeSEA wiki and blog, where he records invaluable results and observations from his 3D printing experiments, which are used as a reference manual for other 3D print engineers and enthusiasts.

After completing the masters degree in Electrical Engineering at the ETH, Zurich, Christoph worked as a software developer - initially in semiconductor industries, and later in life science. Designing and creating innovative software, interacting with customers, and managing a small team of software developers was his passion.

Always taken with mechanical constructions, Christoph designed and experimented with RC model airplanes. With the advent of 3d-printing, Christoph found a new type of creativity, focusing on mechanical watches. His imagination and 3D printing allow him to transform his "crazy" ideas into reality. His belief that future watches will be highly customisable - not only engraving, ornaments or decoration, but real complex objects combining mechanics and electronics - has led him to explore and push the boundaries for 3D printing, combining advanced mechanics and pleasing aesthetics in the process.

Christoph Laimer named as Winner of the Share Prize, 2016

Recently, Christoph was awarded the top prize for his 3DPrinted Tourbillon Watch at the Piemonte Share Festival in May, 2016. The Share festival is an international competition that promotes and supports contemporary art in the digital age. Christoph was awarded the top prize for his 3DPrinted Tourbillon Watch.

This attractive domestic timepiece adds flair to any living room, and is a functional Swiss clock that is almost entirely 3D printed. The Watch is open-source, so every working piece of it is open for inspection, on the web and in the home as well.
