Description
Car is a Datsun 120Y (B210) 1975 but I have a feeling that these caps might fit other models and could very well fit other (japanese) makes also.
I saw a photo of a 240Z wiper assembly and the cap seemed identical but the photo did not show dimennsion so there might be a difference.
I have uploaded a new version!
This thing was made in one evening and as the images show there are some differences to the original.
Rev002 contains a few changes to the previous file (which I took down):
-I have made the shell of the cap thinner to accomodate the ball better.
-The flange now has better cutouts
-The inside of the flange is filleted to accomodate the ball better
-I have NOT made the cutouts to the tab to accomodate turning the cap on the metal wiper mechanism arm (because of a performance issue on my old donkey driven computer). The new photos (blue hued) show that I have filed those cutouts by hand.
I had some issues when printing the top part of the cap since the new shell is thinner. playing with printer settings helped a little but did not make the problem fully go away.
The ball diameter of the wiper motor arm is 13mm and the inner diameter of the lower flange of the cap has been redimensioned to 13 mm also. This works because when the cap is attached to the ball and twister to position the metal arm squeezes the flanges and they are tight.
I have now installed this new cap (PLA version) and we shall see how long it lasts.
This thing was printed in PLA as a prototype but I'm sure that ABS would be the better option due to durability in outdoor conditions.
This thing is no longer a work in progress since the piece fits and works for now. I might update eventually when I manage to get the tap cutouts to work.
I cannot say if they will last the same 37 years that the originals have but then again I can always print new ones.
And so can you now.

Print price estimates
Planning prices for one print, not a final quote. Defaults use a size allowance inferred from the part name, not a measured or sliced model. Filament suitability must be confirmed.
| Filament | USD / print | Application notes |
|---|---|---|
| PLA | $21.50 | Indoor prototypes; not a default material for hot vehicle interiors. |
| PETG | $21.50 | General-purpose candidate; heat and creep need review. |
| ASA | $23.50 | Candidate for UV exposure; verify temperature and geometry. |
| ABS | $22.50 | Enclosed printing; review application and dimensions. |
| TPU | $26.00 | Flexible designs only; not a substitute for rigid materials. |
| Nylon | $26.00 | Moisture, tolerances and application require review. |
| PA-CF | $28.00 | Filled nylon; abrasive filament and fit need review. |
Pricing assumptions and exclusions
USD: ($6 setup + $3 finishing + filament weight × assumed spool cost × 1.25 waste allowance + print hours × $2.50 × material time factor) ÷ 0.65. Rounded up to the next $0.50.
Assumed spool costs per kg: PLA $25, PETG $30, ASA $40, ABS $30, TPU $45, Nylon $65, PA-CF $95. Time factors: PLA/PETG 1.0, ASA/ABS 1.2, TPU 1.6, Nylon 1.4, PA-CF 1.5. These are proposed shop rates, not measured production costs.
Design work, test fitting, hardware, shipping and tax are additional where needed. Multi-file sets may need several prints. Use actual sliced weight and time when available. Final pricing is confirmed in writing.
