Bolt-locked Multiboard rewind filament spool brackets

In preparation for a yet to be assembled MMU3, I wanted to save space by mounting filament spools on my Multiboard setup. The full spool holder build includes: 1 left & 1 right bolt-locked spool holder brackets per spool orient with the flat side down with paint on organic supports on where the axle seats. 2 x 608 bearings per spool (had these on hand) I also tested with print in place bearing with success. 2 x Dual snaps (parts A & B ) per bracket snaps to Multiboard tile 2 x 20 mm Small Thread, Flat Head, T-Bolt per bracket to bolt brackets to Multiboard tile for maximum support. 1 x lengthened Prusa axle from the rewinder (STL included) needed to accommodate the Multiboard tile spacing with a total length of 135mm. 2 x spacers/bushings per spool to support the additional length of the axle with the default spool length, spacers are required. The quickest solution was to use the 608 print-in-place bearings , increasing the z-axis by 158%. This approach worked like a champ! I printed everything in PLA, with a layer height of 0.2, 3 perimeters, 20% infill, random seam, with the brackets using organic painted on supports. These are not hard-and-fast settings, just my usual. Feel free to comment and/or critique, it's all good. side note: rewind spools can impact homing so be sure to release tension after a print or two.
