Glass with masking tape works well with PLA.

Glass with Kapton does not work well with PLA.

Some say heated bare glass works well with PLA.

Glass with ABS juice works well with ABS.

Glass with fabric glued to it does well for everything.

This would indicate that I need 2-3 sheets of glass. I will probably use window glass rather than pop $35 three times.

In my experience, Garolite LE works well with Nylon and PLA. I have not tried it with ABS yet - at least not at the proper temp.

McMaster Garolite LE:

12" × 12"
Thick. Tolerance Part Each

1/4" ±0.012" 8474K141 29.11
5/16" ±0.015" 8474K151 36.17
3/8" ±0.017" 8474K161 43.37

Garolite XX is cheaper. Not machinable, but that does not matter as they sell 12x12 sheets. Not sure how the plastic sticks to it compared to the LE:

Thick. Thick.
Tolerance Each
Opaque Tan to Brown
1/4" ±0.012" 8525K114 $12.86
3/8" ±0.017" 8525K116 18.82
1/2" ±0.021" 8525K118 24.61

I am also going to try gluing a 1/32 sheet to glass.

Glues:

I already tried spray-glue and it worked until I got a heated bed. It did not hold once I heated it.

Now I will try RTV Silicone and Pliobond-25.

We haven't gotten much from Bolt Depot, but I have been to their site and considered them. For our next batch, we got a lot of the vitamins from Timberline instead of McMaster. Timberline is local to us in Colorado, and was less expensive overall. That said, McMcaster is an excellent vendor and very very reliable and fast.

Both my current and former employers (small manufacturers) order from McMaster. It is an incredibly efficient company offering thousands of products. Their product catalog has more than 2 thousand pages.

The advantage of McMaster is it's a one-stop shopping place. For shops and manufacturers it can be interesting because they have everything, no need to open multiple accounts at multiple places. But it's true they don't have the best prices.

I love McMaster. I always get things the next day from them.

Here is my BOM with my costs to far. I will update it as I go along:

I started printing the parts yesterday.

If you are printing a new set of parts, you may want to explore some of the updates that are in here:

http://devel.lulzbot.com/TAZ/

Sorry there isn't a clear changelog of all the changes readily available.

FreeCAD is free to install and open source. It can export to STEP. ;)

I noticed a problem with the jonaskuehling_gregs-wade-ao-v3.7.11.fcstd file. (you guys decided to model it in FreeCAD, cool! :) ) I intended to send an email to Seth about it but I have to go now, I'll probably do tomorrow.

Oh, and a couple of files can't be accessed. For example jonaskuehling_gregs-wade-ao-v3.1.3-idler.fcstd downloads an invalid file with a right-click, and when I left-click on it, I get a 403 forbidden page.

Yes, devel is the development server. Once the work there is considered complete I'm sure those files will be transfered to download.lulzbot and supercede the current files.
