1x spring 0.5mm x 50mm x 5mm (SUGGESTION: order shorter one than me, probably 35mm will be enough)
heat inserts
screws and washer
Instruction:
Insert LM08UU into 3D printed grip
Insert heat set insert
Put the washer on the screw and then the spring
Insert linear rods through the top of the base, but do not insert them into the lower holes yet. Pass rods through the linear bearings in the grip. Insert linear rods into the lower holes
Insert the spring through the hole at the top. Insert the screw through the hole in the mount at the top, then through the spring eye and screw it into the plastic on the other side
(Optional) Prepare platform (insert heatset inserts to it) and mount base to platform with screws
