Printable Linear Bearing and Rail System - Draft 2

thingiverse

The revised design features a bearing system comprising two half-bearing components, one retainer piece, two M3 screws, two nuts, and 32 BBs (16 per race). To assemble the bearing, insert the balls during construction or afterward by pushing them between the retainer and race. Note that some may fall out and require reinsertion. For printing, start with two half-rail pieces and two rail brace pieces; secure these using M3 screws that pass through the rails' holes and thread into the braces. If extending the rail by one length is desired, print two more half-rail pieces and a connector part. Replace one brace with the end of the connector and relocate the other brace to the new rail extension's end. An image showcases a three-length rail containing six half-rail pieces, two connectors, and two braces in total.
