Suppliers close in August. meviy doesn’t. Upload CAD, get EUR 200 off orders above EUR 200. 15 Jul–31 Aug. T&Cs apply.
Milling Parts Standard shipping now runs more competitively on orders with larger quantities, powered by smarter automation.
Design increasingly happens in 3D. Documentation still lags behind in 2D. That gap costs engineers time on every project.
This case study covers Tim Bouwens, a senior mechatronic system designer in the Netherlands. Outside his day job, he runs a personal combat robotics project. He switched his own prototyping and fabrication process from 2D drawings to a 3D-first workflow.
For his bespoke robot parts, the switch was a practical necessity. Manual drawings introduced errors. Competition deadlines left no room for delay. What follows reflects Tim’s personal use of the meviy platform.
If you build one-off parts on a fixed budget and a fixed deadline, his experience is directly relevant to you.

Core challenge
|
- Heavy admin load from drawing every part in 2D by hand
- High risk of errors in dimensions, tolerances and threads - 3D CAD models and 2D drawings kept falling out of sync - Competitions and discontinued parts left no room in the schedule |
|
Why Tim chose meviy
|
- Instant quotes straight from 3D files
- Parts machined directly from 3D data, no 2D drawing needed - Consistent finish quality on complex robot parts - Stable prices, even on one-off, bespoke parts |
|
Capabilities used
|
- CNC milling, CNC turning and sheet metal work (aluminium, steel)
- Surface finishing, including anodising and hardening - Complex geometry, angled holes and tight tolerances |
|
Quantified results
|
- Zero 2D drawings. That alone saves several hours of admin per project
- Quote time down from days to minutes, based on live digital feedback - Zero transcription errors. Bespoke parts now match the CAD file exactly - Costs became predictable, even when iterating fast on a fixed budget |
In traditional robotics prototyping, 2D-based workflows slow everyone down.
On Tim’s own project, manual documentation kept splitting design from fabrication.
That cost him time. It delayed a schedule that was already tight.
The documentation bottleneck
Rising business risk
These constraints raised the risk in production and slowed every project cycle. Tim spent time on documentation instead of design. Iterations slowed down. Innovation suffered.
Without instant pricing, budget decisions took longer. That reduced how competitive he could be.
Over time, transcription errors created quality problems and rework. The fix needed to be structural, not a minor tweak.
Switching to meviy was a practical necessity for Tim. It marked a move to a 3D-first workflow for his own project.
Traditional suppliers were slow and demanded heavy documentation. Tim needed a partner that could turn low-volume, high-complexity fabrication into a predictable digital process.
Four things drove the decision:
Digital infrastructure
Engineers upload 3D files straight to meviy. No 2D drawing required.
Instant quotes and full transparency
Prices update in real time. Tim sees immediately how a change in quantity, material or surface treatment affects budget.
Design-for-manufacturability feedback
meviy flags features that can’t be machined at the point of upload. Tim fixes them before production starts.
Unified procurement
Custom robot parts and standard mechanical components sit in the same digital basket. One supplier, one order.
Quality of finish
CNC milling and turning finishes come out more consistent than local alternatives. Tim compares the process to buying standard industrial parts: predictable, reliable, no surprises.
The result: a standardised digital interface replaced manual guesswork.
The change happened gradually. Over a year, Tim adjusted his internal CAD standards to match meviy’s platform. His models now line up fully with what automated manufacturing needs.
Digital manufacturing turned variable fabrication costs into predictable, off-the-shelf line items. That gave Tim real operational flexibility on his own project.

Even with tight deadlines and discontinued parts, meviy let us iterate fast and keep costs predictable.
I used to lose dimensions or misapply tolerances on manual drawings. That problem is gone.
Tim’s experience is a useful reference point if you’re an individual engineer or part of a hobbyist robotics team modernising your own prototyping process. On personal or small-scale projects with tight deadlines, a 3D-first approach makes a real difference.
How many hours does your team lose each month redrawing parts that already exist in 3D?
Three practical takeaways
Tim plans to bring more complex geometry and lightweight, high-strength materials into his digital workflow. meviy turned low-volume, high-complexity robotics fabrication into a standardised, reliable digital service.
