HP 46/81 idler gear

[RPZ]

I received HP 97 printer gears from Shapeways on Saturday.

From order to delivery was 11 days. Not bad.

No modifications were made except to open the hole with a 3/32" drill.

Checked them by fitting to a printer and feeling by hand for binding or slop.

Some photos are attached.


HP Gear, Light brown

We all know what this is like.


My Gear, PLA, Yellow

Slightly rounded teeth, nice fit. Tested well.


Shapeways, Versatile Plastic, White

Slightly rounded teeth, nice fit.


Shapeways, Fine Detail, Clear

Well formed teeth, nice fit, almost perfect.
Description says brittle but I think they mean in relation to other choices as
it drilled easily and I threw onto my tile floor with no damage.


Shapeways, Steel, Silver

Very rounded teeth, oversize and would not fit, magnetic, very hard to drill
because of the added bronze. Did not plan to use anyway, but so many possibilities.


I plan to use my PLA gears that were tested for 40,000 print cycles but the
Shapeways gear from fine detail plastic is really nice and I think the best 3D print.


Regards, Rick
