My first attempt at a useful thing. I'm learning openSCAD in anticipation of receiving my printrbot+ and I thought I would make something useful. This is a parametric pillow block. At least I think its parametric... (still learning the ropes here) If you change the parameters at the beginning of the file you can change pretty much everything and get a nice customized pillow block.

you can even make it into a bushing by setting the "lip_size" to zero and increasing the "bearing_thickness".

Edit: version 0.2. I fixed a mixup between diameter and radius and added some more comments. The SCAD file is theoretically set up for a 608 skate bearing with tabs for m5 bolts.


since I am still waiting on my printrbot+, I have not printed this ... yet.

Thanks for the parametric file.
I had to fix the openscad version as bushing outer diameter was used in place of radius in the script for generating cylinders.

Nice work, I had to use the old fitter's trick of putting the bearing the freezer for a bit before it would fit, but now it's just perfect :)

I printed the ready-made STL-file and 608-bearing fits nicely. Those holes for m5 seem a bit tight, but it may well be due my printer settings.

You just made my day!

Yep that's parametric. :) Good work.
