I wanted a guide to help me use the bandsaw to cut out curves more accurately. Instead of following a line drawn on the wood I place a template on the surface, the guide follows that template exactly. This uses 1 Magswitch GripRight 90 https://magswitch.com/collections/new-products/products/magswitch-magmount-150-gripright-90-degree-switchable-magnet and:

2 M5x5 Flathead bolts

4 M4x25 Sockethead bolts

3 M4 Flangenuts or regular M4 nuts

You could also just mount this guide on a block of wood and clamp it to your bandsaw table. The height of the guide adjust with one M4 bolt that I used a knurled knob on from this user ( https://www.printables.com/model/441885-knurled-m3-m8-thumbscrews-no-support ) The tip is easily replaceable in case you slice it with the bandsaw. Everything prints without supports. Happy Printing!

PS If you want taller TTrack all the parts fit perfectly in the Rockler T-Track.
