Description
edit: forgot to share the fusion link https://a360.co/36jcJoQ sliding block for 1'' ID steel tube , it rolls over 33.4-33.7 mm OD TUBE using 6082rs bearings It is designed so two tubes can be bolted together for more stiffness and the rail still runs clear over it, or to use as a base a 20x0 profile it is meant to be modular. you can add as much of them aligned as you need. this thing works by joining this modules together using 4mm threaded rods. there are 3 versions. one of them is a stiffer version who lacks the folding hole on the middle. other one has a 0.2 mm offset on one the rollers to the middle ,that offset is meant to fix some issues u may have on your machine ( so please, please, square your machine before u print any of these ) if your machine aint properly squared you may print this one by one on the midle of the bed. so all the modules will be exactly the same an offset of 0.05 on one of the wheels will make them not get in contact with the tube. but that can be fixed. you have vertical holes (to open the wheels ) and a horizontal hole to increase precharge on the rail. it works and it works reaaly fine. remember the gas pipe tube ( IRAM 2502 ) has a fine layer of black/grey oxide that peels away fast so you may have to fix the pre-charge of the rail eventually. you may also get some better pipes like the ASTM A53 1'' ones. they rock. wall width can be get from 2.77mm to 9.09mm stiff A.F. the xxl wall width is really expensive. you may just get the cheap one and use a 20mm alu profile.
