Wanhao Duplicator 7 Build Plate Goodies

thingiverse

Two annoying things addressed by these parts: 1. *Resin accumulated above the build plate* - this is solved by a **cover** that embraces the bracket holding the build plate. The bracket is entirely inside so that no resin will get to the fixing screws and the holes in the bracket. There is some additional displacement of the resin, which you have to pay attention to when filling the vat, and may require some time before print. The holes to fix the whole assembly (build plate + cover + bracket) are extended so if you want to correct the eccentricity of build plate mount in some older versions they will also fit (4.5 mm offset from the standard position). 2. *Need for a screwdriver when leveling the build plate* - I found this pretty annoying hence some **M4x16 hex cap screws** where provided with a **2-part knob**. Just put the screw in the body part, make sure the hex cap is well fitted (best tighten with a M4 nut), put some superglue around the hex and press the cap part on top. Use 0.4 mm extrusion width and 0.25 mm layer height for best fit and use PLA to avoid chemical impact of the resin, particularly for the cover. Perhaps some more exotic material, e.g. ASA, would work too. Knob body also requires support in the hex hole. Attention! Check the distance from the screwdriver rod to the the slider mount, to make sure that your homing configuration allows enough space for the neck of the knob body. There should be minimum 5 mm to avoid mechanical issues.
