Breaster cones

[LomaeArts]

We needed some breaster cones for the finisher. Both local supplier here (Rihanna Footwear and Leffler) don't have our size.
So I made some with a little math help and my 3D printer. The first one was glued with super glue, I will move to high temp epoxy if the glue fails.

Yesterday I pushed about 20mm of 6mm sole leather into it. I need to work on the joint as I can feel the bump.

Nicely done on the 3D printed template forms. My suggestions:

On the 3D printed templates.

1) Increase the nozzle end temperature and filament compression.

2) At your direction changes in the template "Cutting" and "Marking" templates at the four corners do a 0.25 mm fillet so the filament is laid down as a radial turn rather then a 90 degree turn. That way the head speed doesn't have to slow down as much to make the turn which will decrease your print time.

3) I would change the "Cutting" and "Marking" from being indented to being raised markings which would decrease your print time.

4) If the bed of the 3D printer is to small to allow you to print say the "Cutting" and "Marking" template as one unit change you design slightly by putting in joining slots or shapes.

I would try:

1) cutting the ends of the sandpaper so they join together at say a 45 degree angle.

2) Then super gluing some thin 1" nylon binding tape to the back side of the sand paper so 1/2" is glued to each end. Then the other end is butt ended to the first part and supper glued to the other side of the 1/2" binding tape. That should eliminate the overlap ridge / bump and as it rotates you don't have the whole joining edge of the joint striking the leather at the same time. It may or may not work but maybe worth a try.

I understood not one word of this post. Please explain what a "breaster" cone is and what's it's purpose. Thanks.

Basically sanding the edges of leather sorta like those various shapes of sanding / honing cones used on dremel machines but on a lot larger scale.
