Completed the big Tantillus design and I’ve cut and drilled the frame. Even without the Plastic corner covers and the 2020 corner brackets I intend to use, it’s very square and very sturdy - Good start! :). Files and a BOM will go up on Github once I’ve test printed all the parts to make sure they work.
@Paolo_Amboni Thanks 
I can’t take full credit as its derived from a smaller T-slot design. The largest parts are the Z axis mounts a 165mm long but that could be trimmed down to 150mm quite easily or they could be printed as 2 halves.
Working on a similar project, but smaller. I could help you, and you could help me. The only problem i see is that the 608ZZ could go out if the printed part is not really well done.
I will follow this project!! Really good design.
My design is here https://lh3.googleusercontent.com/-CHY59E9Flhk/Ue26qg8YNjI/AAAAAAAABqQ/ragfWuH_zLo/w1538-h865-no/blue.JPG
Awesome work Tim, I like the minimal but robust design!
looking good.
@Tim_Rastall will you be sharing build instructions? I really like this design.
Beautiful, this is a nice nod to the Ultimaker gantry it’s inspired by. Excited to see first prints. The external gears look like a pinch hazard for fingers and hair. Maybe a minimal printed safety cover would fix that?
Sorry for my late entry, but is this like you are using a 3d printer to print the parts of a bigger 3d printer or something ?
@VCSekhar_Parepalli ideally that’s how a RepRap would work.
@Albert_Campos_Merola . They are actually 6900zz as I’m using 10mm outer rods as the build volume is much larger than a vanilla Tantillus. If they are a bit loose, I’ll apply a bit of abs glue yo secure them.
@Steven_North @Paolo_Amboni Yes, designs, assembly instructions Bill of materials (parts list) will all be published once I’ve confirmed it all works
@Hassan_Rostam BOM=Bill of Materials or parts list if you prefer.
@Luis_E_Rodriguez You’re quite right about the pinch hazard, they are also a bit noisy according to the people that use them on the original Tantillus. I’m working on an enclosure that’ll also let me lubricate the gears without getting grease everywhere.
@Paolo_Amboni print surface is (about) 325mm a side.
@Tim_Rastall I’ve heard, but not confirmed myself, that a little graphite powder makes a good lubricant for printed parts.
@Paolo_Amboni Sublime, the guy that designed the original Tantillus isn’t worried, so I’m trusting his judgement for the moment. As I’m using 10mm rods in the outside rails it’s very hard to find GT2 pulleys with a 10mm bore that don’t cost a fortune. I’m also looking into some specialist stunt kite braid that’s supposed to be even less stretchy than Spectra.
