Spacer Dimensions Outer Diameter (OD):

50mm

Height (H):

20mm

Wall Thickness (WT):

5mm

Set to 0 for a solid cylinder, or half of OD for a solid cylinder. Otherwise, creates a tube.

Hole Configuration (Through Faces) Number of Holes:

Hole Diameter:

5mm

Hole Pattern Radius:

15mm

Distance from center of spacer to center of holes (PCD/2 or BCD/2).

Hole Start Angle:

0deg

Angular offset for the first hole from the X-axis.

Export Model

Export the custom spacer/cylinder as a single mesh.

Cylid Holes Spacer

Create a 3D spacer, cylinder, or tube with adjustable dimensions, radial through-holes, and OBJ or GLB export.

What this tool does

Cylid Holes Spacer generates a live 3D model from a few dimension and hole-pattern controls. It can create a solid cylinder, a tube, or a spacer with through-holes arranged around the part.

Who this is for

3D-printing and CAD hobbyists making quick concept geometry
Engineers checking a simple spacer or bolt-circle layout
Students learning how parametric dimensions change a 3D model

How to use this tool

Open Dimensions and set outer diameter, height, and wall thickness
Open Holes to set the hole count, hole diameter, pattern radius, and start angle
Rotate the model to inspect the generated geometry
Open Export and download a single-mesh OBJ or binary GLB file

Inputs

Dimensions are controlled in millimetres: outer diameter, height, and wall thickness. Hole settings are count, diameter, pattern radius, and angular offset in degrees. A wall thickness of zero creates a solid cylinder; other values create a tube or spacer.

Outputs

The page renders an interactive Three.js model and provides OBJ and GLB downloads. GLB is recommended when a compact file with material information is preferred. The generated geometry is a concept model and should be checked in a CAD tool before manufacturing.

Example use cases

Explore a four-hole spacer around a bolt-circle pattern
Compare a solid cylinder with a hollow tube
Export a quick concept for review in a 3D or CAD application

Frequently asked questions

What dimensions and hole settings are available?

Set outer diameter, height, wall thickness, hole count, hole diameter, pattern radius, and angular offset in degrees.

Which formats can I export?

Download the generated spacer, cylinder, or tube as OBJ or binary GLB. GLB is useful when you want a compact file with material information.

Is the model ready for manufacturing?

Treat it as concept geometry. Check clearances, wall thickness, mesh validity, and manufacturing requirements in CAD or slicing software before making the part.
