Tool Vevor Drill Bit Sharpener Improved

I updated the parts folder to include 4 new parts.
One is a generic motor support bracket that is intended to friction fit under the far end of the motor so provide additional support for using plastic only motor mount.
Then I've added a new "20G motor mount" that will allow for the proper positioning of the 20G wheel relative to the standard 13A/B/D grinder seat. The base set back 4mm and has extensions that insert into the slot in the base plate. It also has a boss to install a heat set insert for the cover screw.
I've added "20G B block" that centers over the chuck over the rear of the 20G wheel, and I've added a "20G A Block mount" which positions the standard A tool insert over the front edge of the 20G wheel.
The download folder is still found here
Does Yotabota need these printed?

He does not have a 20G wheel as far as I know.
If he wants to sharpen up to 20mm drills he needs a 20G wheel, and ER25 chuck and Er14-20 collets to do so, with the 20G mod parts.
He has missed our bulk order, so I think he doesn't need that capacity perhaps.

I should have both 13D parts and 20G parts in hand by the end of the day tomorrow, after I return from the woodworking show.
I'll see if I can just slam in some 8mm bolts to do a down and dirty test grind tomorrow night with the 13D conversion. I'll need to go to brother's to secure a larger bit to test the 20G setup. I'll have to improvise on the bit projection for wider the 13mm drills. But I think that the projection is the same as the drill diameter on the normal set-up. The 20G may just cause the addition of a mm or so

NAH lets just have @DavidR8 print the support block too. Low infill, low wall count, down and dirty is all you need. Then it can be left in place.
I am sorely tempted to make parts of plastic and leave them in place, after I've printed optimized parts. If I wont need to mill metal why would I...
"Why would I",,,,,, Your a funny guy! lol
I will probably fit the support and then MILL a couple of slots in the base for screws up into the support.

If you want to do that I'll modify the part to accept a heat stake insert, to do it right.

I have a new part "motor support with insert holes", that has 5mm heat stake insert in the top. The holes are 15.1 mm from the edge, and 58mm apart

The insert on the side is 5mm insert.
The bottom of the motor mount is threaded into the plastic since the hole is deep it should hold fine, and an insert doesn't fit in the projection.
The top of the tool blocks are have an 8mm thread profile for now. I did not select an insert hole for it yet since it is prototype and sadly because I don't have 8mm inserts at the moment. I do have a buttload of 8mm taps to run thru the threads though.
The 2 holes on either side of the 8mm threaded hole are for 5mm guide rods. The guide rods are loctited or superglued into the hole in the motor mount. The 8mm grub screws need a profile machined in them and roll pins to hold them in place in the motor mount.
