ce-net / design

Small CAD jobs at a fixed price.

Add a hole, make a part fit, draw a bracket from your measurements. You pay a fixed price instead of an hourly CAD rate, and you get the part back as STEP, STL and a PDF drawing, checked printable. If you want it made, a print shop in the ce-net network prints it.

How we work: the CAD is done with the same tools that built the parts further down this page, and every file is checked against its drawing and sliced in Bambu Studio before it goes to you. Simple jobs only: anything larger gets a quote through CE Engineering.

See it run before it is made

We build the part or machine in CAD and run it in simulation first. Two recent ones, below. On a 20-minute call we show yours.

A factory, simulated. Machines, robots and people on one floor, rebuilt from one walkthrough video, so a line can be planned before anything moves.
Huey, a small two-legged robot with a painted head and a face screen (design render).
Huey. A small walking robot with 15 servos and an LED-matrix face, designed, simulated and printed in our Shenzhen workshop. Design render.

How a job moves

  1. Send itThe file, a sketch or photos with a ruler in them, and one sentence on what the part has to do.
  2. Fixed price confirmedWe tell you which of the three jobs it is. If it is bigger, we say so before any work starts.
  3. Drawn and checkedParametric CAD, a drawing measured off the solid, and a real slice to prove it prints.
  4. DeliveredSTEP, STL and PDF by email, on time. Want it printed? Say so and a shop near you makes it.

Parts we have drawn

All of these were designed with the same tools that do your job. The pictures are the real CAD output and the real prints, not illustrations.

CE Mold, a printed casting mold. A two-part PLA mold for a silicone sensing pad with four electrodes inside: seats for the electrodes, a clamp for the ribbons, pour funnel, vents and bolts, checked in CAD. A design sample, not yet poured. See it in 3D.
CAD render of a two-part clamp holding a 4 mm hex bit, seen from four sidesThe printed clamp standing on the bed of a Bambu Lab A1 printer
A change to someone else's part. Seeed's robot gripper finger (their STEP file), changed to clamp a 4 mm hex screwdriver bit with one M3 screw. Seeed's four-screw mount is left exactly as it was. Printed in PETG: 17 g, 1 h 26 min on a Bambu A1.
Exploded CAD view of an RC car frame: floor, bumpers, servo mount, electronics cage and body postsEngineering drawing of the chassis floor: three views, a section, a hole table with 16 positions and a title block
An RC buggy frame, 16 parts, 13 drawings. Every part has a STEP file, a drawing with a hole table measured off the solid, and a print file. The whole car is 143 parts over four assemblies with 68 PDF drawings. Tap the drawing to see it full size.
Render of a corner where three custom aluminium extrusions meet a printed corner node, with a blue panel held in the slot
A custom aluminium extrusion. A square profile that carries an LED strip, its diffuser, a panel and the wires inside the bar, plus the corner node that joins three of them. Drawn for a cocktail machine, with the die drawing notes for the extrusion maker; the corner was test-printed on our farm.
