We just put up our acrylic carriages if anyone needs a set!
These are precision cut to fit Misumi 1515 aluminum extrusions without any offset nuts or any required tightening of the wheels. The front of the carriage also has 2 mounting holes that are 35mm apart for mounting joints for the arms. Each carriage is tested prior to shipping.

Great! Now how about some cheap international shipping? A set of rollers & carriages for $55 gave me cheapest shipping to Czech Republic at $94! 
+Peter van der Walt I’m sure they don’t do it on purpose - probably just an incorrect calculation or wrong product weight… Let’s hope @Shai_Schechter will be able to offer us a much better deal 
Crap, really sorry about that guys! Will get to it immediately.
Are you guys getting overcharged on priority flat mail? If you could send me screenshots of the shipping you’re getting to info@deltaprintr.com with your address so we can see what’s wrong, I’d really appreciate it!
Ok, I think we fixed the issue. We had the less expensive shipping methods disabled by accident. See if it works now guys.
If you think you’re still getting an overpriced shipping method, please send us a screenshot of the shipping calculator to info@deltaprintr.com and we’ll sort it out for you.
Sorry for the hassle!
