Cheers for that I noticed they did printed format when I was downloading the program for converting the file to Kindle format but hadn't looked further into it, I shall have to read more. The conversion program has a neat simulator so you can see what it will look like on a Kindle fire.

I've always preferred print to digital. I dunno why.. i just find it an easier read.

i think i would probably buy it. :)

Just about finished my latest creation, I haven't quite decided which name to recycle for it yet.
It's printed in the usual Alloy 910 Nylon with six small lathe parting off tools mounted in the drum at 120 degree offsets.

Very nice as usual, Peter. I'm going to have to read back through your thread to see what you've been up to.

Looks great! :D really inspiring as the design in a similar principle to what im trying to build at the moment!
Can i ask how heavy the chassis was to hold all the parts? And also the brand of drive ESCs. That's the last part in struggling with (Shakey's ESCs are out of stock)

Using the toothed belt rather than smooth tensioned belt is better?
Weapon test video! :D

The chassis came out at around 27 gms, the drive esc is an own designed module see page 44 of this thread.
As expected with a 3D printed drum there is some vibration as below.

The sharp eyed amongst you probably noticed that although the latest drum spinner was printed mostly in nylon the two belt drive gears were still in polycarbonate as it generally gives a more detailed finish. I have been getting such good results from the combination of my new printer and Cura2 that I decided to try printing the gear in nylon and it has come out very nicely see shot through my microscope camera without any cleaning up.
