Ender 3 Y conversion to linear rods

My conversion Ender 3 to linear rods.

Before conversion I had 30-32 Hz on Y axis, now it's 43.25 Hz.
Printer works best in range 2000-2500mm/s2 acceleration. Normal speeds are up to 150mm/s for technical parts and 50-80mm/s for organic, like faces and such. Mind you, those numbers are from Klipper. In Marlin think about reducing them for about 1/3.
Regained entire 235x234x250 build volume.

Bottom frame is replaced with 2x 450mm and 2x 250mm 4040 extrusions to make place for rods.
Rods are 2x 450mm fi10 with 3x linear bearings in housing.

Electronic enclosure is moved to the left side. One 6020 24V fan reduced to 12 V (for noise purposes) is used for cooling. The old stock enclosure would probably fit inside frame, but I didn't test it.

All parts except electronic enclosure should be printed with PETG or CPE.

Drill plates are helpers for drilling holes in extrusion in the right places. Rotate them appropriately to drill 5,5mm holes, then rotate drill plates to widen ho
