Is there a more complete BOM around? Granted most of us could piece this together, but I'm curious as to what motor you're using for the Z-axis.

What is meant is you warm the bearing to the point that when you insert it into the bearing hole that it melts the plastic a bit so it slides into the hole. Shane QuoteRalphxyz Quotenicholas.seward I put the part in an oven on low. I take it out every minute and hit it against a hard surface. When the tap turns to a thud you are ready to insert the bearings. I have heard reports that you canby sgraber - Delta Machines
I have to think you used 25% infill on everything but the HUB BOTTOM.stl. I just sliced all the files using 15% infill with your above-mentioned recommendations (50% infill on HUB BOTTOM.stl) and come up with 33 hrs printing and 665 grams of PLA. Did I miss a part??? I thought I understood that GUS took ~1kg PLA. Here's my slicing results: And here is my slicing settings (Slic3r): Shaneby sgraber - Delta Machines

+1 Quotenicholas.seward @iquizzle: I think we should embrace the idea that people will want to make a business that runs on open source ideals. We owe Ubuntu to a company for example. While I think that RepRap at its core has nothing to be afraid of there are some businesses that RepRap directly and indirectly benefits from that do have reason to be afraid. I propose we do freak out and we dby sgraber - General
FWIW if you want to compare your filament usage and print times, take a look at a page I setup for myself while I was making plates for printing for Smooshed: It's a bit convoluted, but it gives you an idea... (Edit: I need to update the print times as since making this I have tweaked the printer to print faster, thereby saving ~5-7 hrs over a 45 hr print.)

QuotecdsteinkuehlerHmm...I like the honeycomb infill, particularly at low infill ratios (since all layers are supported), but I wonder if that's it.

I'm using a combination of printers: I printed half the parts on my Prusa i3 (https://github.com/josefprusa/Prusa3-vanilla) and the other ones on my Prusa/Graber i3 (https://github.com/sgraber/Graber) Filament: I had to switch printers mid-print as I had access to 1.75mm filament but my Prusa i3 uses 3mm filament.

FWIW, I just printed an arm with WALLY on it and had no problems with it adhering well to the build platform. Printed in 1 hr 45 min. 3 perimeters, 15% infill, 0.3mm layer height, 65C bed temp for first layer, dropped to 60C after that, hotend at 205-210C, used hairspray on the heated bed.

FWIW TrinityLabs' hobbed pulley is a standard MK7 hobbed pulley, so any pulley made to Makerbot's MK7 dimensions should work. I know TrinityLabs, Makerbot, and SeeMeCNC all carry their own versions of the MK7 hobbed pulleys.by sgraber - Polar Machines, SCARA, Robot Arms

Really I just wanted an excuse to print one. I showed the SeeMeCNC deltabot guys (RostockMAX guys) the parts on Monday at their shop and they were really impressed with the size of the parts!

IMO after printing almost a complete Wally set over the last couple days for @Smooshed, I really think you're going to lose strength and rigidity going below 15% infill and going to a hollow part. I wouldn't do it. You'll save a bit of filament but sacrifice part rigidity, not to mention introducing problems when holes widen or start in the middle of a part, which then would require printing wiby sgraber - Polar Machines, SCARA, Robot Arms
I would interpret that as cubic centimeter of filament used. When you slice a model with Slic3r, if you look at the very last line of the generated gcode file it will say something like: ; filament used = 4135.2mm (29.2cm3) That is what I'd think that volume quote would mean if it were me. At 1kg material (1000 grams) using a density of 1.1 g/cm^3 for PLA, 1 kg of material would be 1100 cm^3by sgraber - Polar Machines, SCARA, Robot Arms

Whenever I've printed for people, I normally charge plastic cost times 3 or 4 depending on machine time and how much I need to baby sit the print. 1kg of PLA runs me right around $20. Does that put it out of the ballpark for people? If not, I'll print for you guys. I've checked with Nicholas and he's OK with this as it gets some Wallys in the wild.by sgraber - Polar Machines, SCARA, Robot Arms
Honestly I'd have to check to see how much plastic it uses. Was the approximation 1kg?by sgraber - Polar Machines, SCARA, Robot Arms
