5 Attach Feet to Y-Corners

Attach one flexy bed foot [PP-GP0238] to each Y-Corner [2x- PP-IS0089 & PP-IS0090] using one M3x10 BHCS [HD-BT0148] with washer [HD-WA0038]

Tighten the fastener until it begins to compress the flexy bed foot and the foot can no longer rotates easily.

attach flexy bed feet to all 4 y corners

6 Assemble Bed Mount Table & Y-Corners

Place two extrusion [HD-EX0062] horizontally with two T-nuts [HD-NT0053] in each extrusion.

Place the Y bed mount table [PP-GP0395], as shown, with the first layer print surface angle facing each other.

Secure the bed mount table with a [HD-WA0040] M5 washer and [HD-BT0073] M5x10 screw. These fasteners do not need torque applied yet; they will be adjusted during Final Assembly.

Insert one Y corner right [PP-IS0090] & one Y corner left [PP-IS0089] on each extrusion, as shown in the example photo.

Secure the Y-corners using T-nuts [HD-NT0053], M5 washer [HD-WA0040], and M5x10 screw [HD-BT0073]. Repeat for both sides and torque these fasteners to 5in*lbs
