Multiple small parts means many opportunities for things to go wrong. A systematic check after printing — and a verification process — catches issues before they become problems.
Print verification.
Use these three in order. Each builds on the one before.
In one paragraph, explain print verification.
Walk me through diagnosing a 'cable too tight' issue.
I'm printing 50 clips for a workspace. How do I verify efficiently?
AFTER PRINTING:
CHECK EACH PART INDIVIDUALLY.
VISUAL:
- Does it look correct (no warping, no missing features)?
- Is the surface acceptable?
- Are sharp features intact?
DIMENSIONAL:
Use calipers.
- Length, width, height: match CAD?
- Hole sizes: match expected?
- Wall thicknesses: match expected?
Document any deviations.
FUNCTIONAL:
- Does the cable holder accept the intended cable?
- Does the clip grip the desk edge?
- Does the raceway hold cables securely?
Test with actual cables.
IF SOMETHING'S OFF:
UNDERSIZED HOLES:
Cable doesn't fit.
Fix: enlarge the holder in CAD; reprint.
OVERSIZED HOLES:
Cable slides out.
Fix: tighter holder.
WRONG SHAPE:
Doesn't fit the desk edge.
Fix: redesign the attachment.
ITERATION:
Each iteration: 1 hour of design + 15 min print.
Often 2-3 iterations to dial in.
DOCUMENT:
- v1: too tight on cable. Made holder 0.5mm larger.
- v2: still tight. Made it 1mm larger.
- v3: perfect fit.
Note the final dimensions; reuse.
BATCH RE-TESTING:
If you printed 8 clips:
- Test each on the actual cables it'll hold.
- Some may fit; some may not (cables vary).
Use the working ones; toss/recycle the misfits.
Or: redesign for the misfits if it's a common pattern.
PRINT ISSUES THAT AFFECT FUNCTION:
LAYER LINES TOO COARSE:
Affects clip flexibility.
Fix: smaller layer height.
OVER-EXTRUSION:
Cable cavity is smaller than designed.
Fix: tune flow rate.
UNDER-EXTRUSION:
Cable cavity is loose.
Fix: tune flow rate up.
GAP BETWEEN PARTS:
Slicer issue or design issue.
Investigate.
VERIFICATION CHECKLIST:
For each cable clip:
[ ] Visual: no defects.
[ ] Dimensions: match CAD.
[ ] Cable fits: yes/no.
[ ] Desk attachment: secure.
[ ] Removal: easy.
If all pass: ready to install.
IF FAILING:
Diagnose: what's the specific issue?
- Surface finish (cosmetic): probably acceptable.
- Dimensional (functional): redesign.
- Mechanical (won't grip): redesign.
REDESIGN STEPS:
1. Modify CAD parameters.
2. Re-export STL.
3. Re-slice.
4. Re-print.
5. Re-verify.
Cycle takes 1-2 hours per iteration.
After 2-3: usually correct.
INSTALLATION:
Once verified:
- Install on desk.
- Insert cables.
- Adjust position if needed.
Take photos before/after.
Useful for showing the difference.
DOCUMENTATION:
For your records:
- Date printed.
- Material used.
- Final design version.
- Cable types it holds.
Six months later: easy to remember what worked.
