That was a long time without any signs of life!

Last batch of the printed parts

I bet y’all thought I dropped the project! But no. An unfortunate turn of events didn’t allow me to work on the printer since last update – but not anymore.

Few last parts arrived some time ago, they were X axis carriage, and all printed elements for Y axis: smooth rod mounts, stepper and pulley holders.

And here they are!

I will add all of the stl files to my thingiverse page tomorrow for download.

Another few pieces of the puzzle

All the pieces

Another few pieces of the puzzle arrived, managed to assemble them together and get a little glimpse of the whole picture .) As previously, I’m amazed at the quality of the laser prints – SLS is an amazing piece of technology.

I have already added some of them on my Thingiverse page to download, rest will be added later today.

And here they are:


both X axis ends, one with stepper motor mount.


Z axis module, lower stepper mount, upper smooth rod mount, and an X-end in the middle

X-axis assemble

X axis assembled with short smooth rod – just for testing purpose

All the toys

Tiny, tiny, tiny pulley

623zz pulley for GT2 timing belt

Some time ago I posted a render of the 623zz pulley – a tiny pulley to guide GT2 timing belt. I was aware of the dimensions of the part (well, I designed it to have certain dimensions to fit around 623zz bearing, right?) and this is how render looked:

Pulley for 623zz bearingAnyway, even with me knowing how small the part was – it’s amazing how tiny it is when I received it printed. I hope it will work well, we’ll see… Take a look at it in real world:

And last picture Рstanding on a small coin for comparison:

Told you its tiny!

Yeey, made new thingies!

Another render of reprap parts I made.

After a few days I can get back to you with some updates. I managed to create two parts from scratch – but they are still compatible with Nutz95 design. I have uploaded them to Thingiverse here. What feature I’m most proud of is designing part mount around aluminium extrusions. I have added 8 mm rectangular pins, fitting 30x30x8 mm aluminium extrusions row holes (which are actually 8,2 wide)
