First things first:

I abandoned this project.

While constructing this i ran into so many problems, that i just stoped building a rostock. I think it is still a very unique project and a great idea behind it, but at this time it's not ready for just screwing everything together and it works.
The fact that i'm too lazy to get anywhere deeper into this project made me abandon this. So feel free to use this "as is" and see it as "not finished".

I reconstructed the whole plywood plate, so that it is symetrical and stuff. metric system used
Constructed in Autodesk Inventor 2012.
PDF Image format: DIN A4; 1:3 scale
DIN A2; 1:1 scale
sry for the german names :S


  • changed 6mm to 8mm Holes (thanks smolkd)
  • added dxf file

Can you list the dimensions in inches please

Just a quick note, I did a angle check and the angle comes to 126 instead of 120. is this deliberate?

i did this in Inventor 2012 and constructed it with 120°. If it doesnt have these well i dont know why.

No you are right! I went back and checked it, it is indeed 120. I used the middle of the board instead of the crosspoints. Noob mistake :)


i used your file for making my base and top plates, thanks a lot..

but... for setting up the rest... can you provide the diameter of where the holes on (i need the delte-smooth-rod-offest to be precise ....)


I love this. Its is much better than trying to do it via angles, etc whioch is soo hard to get perfectly accurate. However,
I am confused about the discussion RE the holes here. Unless I am missing something, those holes are supposed to be where the main bolts for the plastic motor housing and pulley mounts are attached at the top and bottom? The rods and belts go outside the edge of this plate?

I just have it laser cut and make two copy of it..
One for bottom, one for top
I guess 8 mm holes is for smooth rods
But here comes the problem,
When it attach upon a plastic motor housing, the pulley will be under the plate,
Belt will be blocked...
I think i have to cut three holes for belts to go through

it's fpr 6mm smooth rods with a distance of 60mm. But you can modify it like you want. Uploading the dxf and unscaled pdf aswell

For 6mm rods or 8mm? If not 8mm, do you have one for 8mm?

you are right. it should be for 8mm rods. but it will also work for them. the centerpoints are measured. Just use 8mm then.
I will update the *.ipt and reupload it

Umm, sorry for commenting but the holes in the plate are now drawn as 8mm dia?

That's kinda wrong isn't it, the rods are 8mm and they go on the outside of the bed. The bolts used are clearly supposed to be 4mm to attach the motor-end and idler-end to their respective plywood. Holes in scad file is defined as 1.9mm radius which to me is a definate tight 4mm dia expected.

could you post the unscaled version too?
pdf is fine, dxf (~R12) would be good too. I guess this is the smooth/round rods version, not the makerslide variant?

sorry, but it seems like i cant export dxf files with this version :( gonna look tomorrow again

You can - right klick on your part - export pane (Fläche exportieren) :-)

it worked. thanks :)
