I found this on thingiverse the other day. I wanted to see how it would print on the Behemoth. The only way it can be made is on a 3d printer. It can’t be assembled or dissambled (at least without breaking it). It printed great and it was very easy to break the gears free and start rotating it. I ran it in a drill a little bit and it loosened up very nicely. I’m not sure how long they will last but I intend to use them in the smaller 1 pound spools.
I picked up a piece of 41cm x 35cm x 3mm float glass at the local glass shop. It weighs in at a hefty 1029grams. I’m printing a 300x300mm square picture frame just as a test of the large surface area. The glass does sag a bit in the center but that can be easily remedied with some supports underneath. So far it doesn’t seem to effect the print.
I think I’ll work on a system to make these print beds easier to interchange. I’d like to be able to put the smaller bed back on there when I need heat on the bed.
This is the second PLA rocket I am building. The first one flew well and is ready for another flight. See it here. The bottom section of this rocket is 300mm tall. I will print a 300mm tube and a 70mm nose cone for a total height of 670mm.
The layer alignment on this section is the best I have ever seen on any of the printers I have built. I was worried about issues surfacing as I printed at higher and higher elevations. So far I have not had any. This one was printed at 0.35mm layer height and took about 2 hours to print.
I measured the Z height again and I can print 390mm high.
