Sheet Metal Brake and 3d Printer.

I think it's closed profile. That's just how sketchup imports them, it's not a great program.
https://drive.google.com/open?id=1OeDvagCIh6nnlw7WHoQM6iVRWrF-CsP8 Here's a link. I can't tell if they're closed in fusion360 either since that likes to shade any enclosed area anyways, or even in that preview of the file.
The only changes i've made to the plates is to include 2 more for Z motor mounts and to en-widen the biggest plates by 20mm in the middle to span the 20x40 Z beams. I left the Y rails at 20x20 since I figured being a bit shorter than in the original design they'd probably be alright.
Also I was going to ask why your dxf files had the parts so far apart. I wasn't sure if it was to make use of a weird plate or something. I guess that explains it!
S. Heslop:
Oh yeah those flanged bearings arrived today. Total trash! I didn't really expect much but I was surprised by how decent the other ones seemed once i'd pulled off the seals. Decent quality flanged bearings cost a fortune in the amounts i'd need so i'm back to thinking those stupid overpriced wheels might still be the cheapest option.
WeldingRod:
:beer: I gave your DXF a check, and all the shapes are water tight!
A word of warning: do a careful count to make sure you have all the plates! The set up and tear down is more expensive than the cutting for this sort of stuff. Thus, much cheaper to get a few extras than to come out short. I ended up with dozens of random bits after the production run of bots...
S. Heslop:
Thanks for checking it, that's a relief to know.
I chickened out yesterday on asking places. I'm fairly certain i'm gonna make an ass of myself. There's a whole bunch of places I could ask so i'm trying to narrow the list down to a few small ones. Sign fabricators seem promising.
S. Heslop:
Nothing better to do right now than go through the list of all the small things I need and price that out. It's my favorite part of any project where the estimated price can double. All those little things add up.
The controller boards... there's alot out there. I'm sure the smoothieboard used to be £100 but they're now £160. There's alot of them about that hover at the same kinda price, but then there's those MKS SBase boards from China for £50. A £110 savings is nothing to sneeze at.
Can't find any outright 'don't buy this!' posts about it. Just the usual 'buy cheap buy twice!' garbage. I could buy 3 of these boards for the price of an official smoothieboard.
