Openbuilds-style Spindle Mount Baseplate (65/71/80mm) · 模型 300093
Wanted a slightly more elegant solution for mounting 65mm spindle brackets onto 8020 extrusion rather than a couple of corner brackets. This is machined from 10mm 5083 plate, and uses recessed M5 dome heads to securely attach the spindle brackets to the baseplate through the rear of the plate, then a machined edge to hold them parallel. I believe this will work for all Openbuilds-style mounting kits but just check they've got 60mm centers on the rear bolt spacing 4x M5 cap head bolts and t-slot nuts are then installed from the front and the entire thing can be installed onto 8020. There is ample access to these bolts on the front, allowing you to tram the spindle much more easily than the original mounting bolts. Hardware requires: *4x M5 dome heads (existing bolts are fine) *4x M5 cap heads (can get by with dome heads if you have enough length on the originals). *4x M5 t-slot nuts. Suggested order of machining: through-holes and counterbores on the front, screw through these holes into your baseboard then you're free to cut the external features. The outer holes do require you to counterbore from the rear; this can easily be done by hand with a M5 counterbore bit and a drill press set at the appropriate height (need a 3mm deep counterbore, but these sit directly above the slots so if they're slightly proud you're not in too much trouble. A suggested modification to the original mounting brackets is making the counterbores on the front clamping plate deeper - I took mine down to 5mm deep, giving me 3.5mm of extra thread engagement on the spindle bracket.
