Workflow
Design custom feet, spacers, and standoffs
Design a replacement foot, spacer or standoff with the required height, contact area and fastener hole. Keep those dimensions editable so you can correct alignment and fit after checking a printed sample.
Set up your part in PurCad
Enter your measurements in millimetres. This prepares a request in the editor; review it before starting generation.
Set the height and fastening interface for a spacer
- Measure required height, outer diameter or contact footprint, and the central screw, hole, or threaded insert.
- Specify counterbore, chamfer, material, compression load, and the two contact surfaces.
- Verify height and seating with a sample before supporting the finished assembly.
Define both contact faces and the fastener
Measure the required separation, available footprint, screw or bolt diameter and any counterbore or captive-nut space. State whether the part carries compression, locates an assembly or only prevents surface contact.
Build the axial interface first
Generate the base profile, height and central mounting feature before adding ribs, chamfers or anti-slip details. Keep height, outside diameter and hole size as named parameters so variants can be created without rewriting the design.
Check height, contact area and connected geometry
Measure overall height and both contact faces, inspect the fastener path and confirm the result is the intended number of connected bodies. Export a STEP file for assembly work or STL and 3MF for a physical fit test.
Geometry alone does not establish load capacity
Material, print orientation, buckling and sustained compression determine how a support behaves. PurCad does not certify load capacity. Test structural or safety-relevant supports with the intended material, fastener and load case.
Practical questions
How do I size a 3D-printed spacer or standoff?
Start with the exact required height, fastener diameter, contact area, and clearance to surrounding parts. Check compression and alignment with the actual assembly because printed material can deform.
Are printed feet and spacers strong enough?
Strength depends on material, orientation, geometry, load, and long-term creep. Use a physical test with the real fastener and load; CAD validation does not certify load capacity.
