Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
The zero play guide bar system is a huge benefit for anyone making and using jigs in a climate where conventional wood guide bars will expand and contract. I will use this with my table saw miter slot but you may find it useful with your band saw or router table.
Microjig has devised a nice solution https://www.microjig.com/products/zeroplay
I relied upon the users manual to inform my design and hardware choices.

This current model has adjustability to fit slots from 0.688-0.774in (17.5-19.7mm)
***STL UNITS ARE IN INCHES***
Each guide piece is 8.94" (227mm) long. One guide set will fit diagonally on a 200mm x 200mm build plate.
There are two configurations for this design. One uses heat-set inserts, one uses a little bit longer fasteners into low-profile hex nuts.
