hi man, nice work, but they do not interlock after printing, can you ajust the dimention, thanks

you need to adjust the "perimeter inset" parameter to fit your printer. The tolerances are pretty tight. I think in cura it's actually called "horizontal expansion" and you need to put a negative number there

I am going to try, thanks

Very nice, love your design. I am looking forward to print some modules.
Just a quick question:
Would it be possible to get a version for 5 ml Test Tubes (like these: https://online-shop.eppendorf.de/DE-de/Spitzen-Reaktionsgefaesse-und-Platten-44512/Reaktionsgefaesse-44515/EppendorfTubes-5.0mL-PF-156668.html) or do you know if they fit in the 15 ml conical tube modules?

I do use those 5ml tubes in the 15ml holders. It's a bit tight but it works.

People have had trouble with the racks not fitting together so here are some tips:
1) print the outer perimeter first. This setting is really important to getting accurate dimensions.
2) you may need to decrease your extrusion multiplier a bit. A lot of people print with overextension all the time and don't notice it.
3) do fewer perimeters. Two is usually plenty for these racks
4) don't use a brim or support or anything

Good luck!

Nice, i will try that!
And thanks again for the designs.

Thank you so much for this, this is great!

They work great to fit the tubes I made them for (50 mL and 15 mL), unfortunately they do not interlock after printing with our machine (LulzBot Mini). Not sure if it's just my machine though. I don't have a lot of experience with design, would you recommend that I try to make the protruding nubs smaller or the pockets bigger?

Fantastic! My wife has been bugging me about tube storage for her beading supplies. I know that is not what this was meant for, but it will totally work. And it's infinitely expandable.
