Rhino & Grasshopper training on your own project.

You find the form. The file should do the rest. I show you how: find the form, make the road to it repeatable, hand the routine to AI. Everything I show you, I designed and built myself.

02Who it is for

Who usually sits with me

Almost always someone who designs, and wants to touch the result. Laser cutters, CNC routers and 3D printers now sit in workshops and studios that once held only hand tools. What gets stuck is rarely the machine — it is the road from the idea to the form, and from the form to the file.

Makers & artists

A laser cutter, CNC router or 3D printer of your own

The idea is there, the machine is there, and between them sits the good part: try it, throw it out, try again. We make that road short enough that trying things is a pleasure again — all the way down to what the controller wants to read.

Freelancers

Product design, furniture, objects, stage

You design and fabricate yourself, and every variant costs you an evening. We set it up so the next one takes ten minutes. Ten minutes a variant means you see twenty before you decide, instead of two.

Students

Architecture, industrial design, product development

€ 89 instead of € 179 per unit against proof of enrolment, € 69 each from three people up. Above all for anyone who has to build something in the university workshop and finds that design and machine speak two different languages.

03Where to start

The Clinic

One hour on your own file. You show me where you are stuck — in the form or in the making. I tell you what is causing it and what it would take. No course, no commitment.

€ 59
1 hour · fixed price · incl. VAT

The most common way in. Many stay for a full course afterwards — but nobody has to decide that beforehand.

04Evidence

The same file, a few weeks later

On the left the Rhino model, on the right the finished shelf: six metres long, two metres tall, in 19 mm pine. The wave was not calculated, it was looked for — move a slider, look, move it again. Only then come unrolling, nesting and a slot plan that has to work out to the millimetre. I teach both: the looking and the building.

05For workshops

And when a whole company is behind you?

Then it is rarely about a tool but about the workflow: where variants cost time, what gets lost in handovers, which routine nobody ever automated. Parametrics and AI go exactly there.

From people who sat through it

“
The one-to-one Rhino 8.0 training with Björn Jelinek in March 2024, split across several online sessions, moved me forward enormously. Since then I understand Rhino far better and faster, the models are more accurate, the results are many times better, and it is simply fun to build really cool things with Rhino.

“
The Rhino 8 course with its focus on Grasshopper exceeded my expectations, thanks to Björn. As a beginner I benefited from his clear, step-by-step explanations. Topics covered the interface, 2D and 3D design, SubD and Grasshopper. His practical, professional approach helped me understand real applications. An absolute recommendation for anyone learning Rhino 8.
Georg Muellerlong-term student

I watched Björn work with Rhino and Grasshopper a great deal, and either he already knew the answer or he had good, creative ways of getting to one. What he has built in the way of tools is genuinely impressive. Whenever I came to him with a question he could always help, and I had the feeling he enjoyed doing it.

Talk first, plan after

A short call to work out where you are and what you want to build. After it you get a proposal that fits both — or the honest answer that you do not need one.
