Thin knob for M3 nut

thingiverse

My Discoeasy has a bed level defect but the bed is not adjustable in standard at first. I could only print small parts so I designed a small part to address the issue. This knob has been designed for use with the self-locking nut provided with the Dagoma Discoeasy 200 to fix the bed effectively. For each bed support, you need to use a specific combination of components: - A 25 mm countersunk head screw - A small spring (I re-used old springs but something like 5mm x 10mm) - Two standard M3 nuts Place the self-locking nut inside the knob securely. Fix the screw on the bed with a standard nut tightly. Screw the knob from the side facing the bed firmly. Repeat this process for each hole on the bed. Next, place the bed on its support system carefully. Put the spring on the screw located at the back of the support. Screw the other nut to keep the spring in place (this part requires some finesse!). Repeat this process for each support unit. Now, you can adjust the bed level by screwing or unscrewing it with a wrench or by hand. Ensure that the knob is in contact with the support at all times. I've tested this solution and it works perfectly for me. I'm now able to print without any issues. I designed this system because I wanted the spring to be located under the support, pulling down the bed, rather than between the bed and the support, pushing up the bed like other systems.
