01
The "spool" concept
The very first CAD: a simple spool with two flanges and a central hub. The basic idea — a roll that unwinds the fiberglass veil in a guided way.
Our story
Nine steps.
One dispenser.
From on-site experience to Made-in-Italy innovation: how VELOBOX went from a simple spool to its definitive design.
2025 — 2026
01 — The problem
On-site experience
Unrolling the fiberglass veil by hand, cutting it with a knife, wasting time and material. A gesture never modernised — and the origin of VELOBOX.
02 — The evolution
The design story
Two turning points guided every iteration:
Round → Hexagonal
The star shape, more ergonomic with an enclosed housing.
Metal → Plastic
A single-piece cutting flap, zero metal components.
02
The first physical prototype
The first 3D print: a cylindrical body with a top bridge and the tape exit slot. The concept becomes tangible and testable.
03
The hand-crank cylinder
CAD development of the two-part cylindrical body: a central spindle, a clover hand-crank to rewind, and a cutting blade. Measured dimensions: Ø 91.5 × 70 mm.
04
Prototypes with metal parts
The first printed units (in blue) use a metal cutting blade and belt clip. Weight and function tests with real rolls.
05
From metal to plastic
The materials breakthrough: metal is dropped. Cutting flap and belt hook become integrated plastic, with interchangeable end-caps for quick roll changes.
06
Exploration: discs, bracket, hexagon
CAD studies on ergonomic discs and a top handle. This is where the male-female hexagonal peg coupling — inherited by the final design — is born.
07
The hexagonal "star" turn
The body becomes a hexagonal star — the definitive shape. A hexagonal-socket hub and a ribbed belt arm integrated into the shell.
08
Refining the closure
Refinement of the male-female hexagonal peg and the top tab: the two shells couple firmly and open with less than 1 kg of force, even with gloves.
09
The final design
The definitive VELOBOX: hexagonal star body, 3 interchangeable adapters (fiberglass veil, perforated paper, mesh), a single-piece plastic cutting flap, zero metal, and a belt hook.
03 — The result
The finished product
The definitive hexagonal design, printed and ready to use with the fiberglass veil roll.
