Printing in Bridge Nylon, which consistently fails to adhere properly on the print bed. To combat this issue, the cover design will eliminate draughts and an additional step of drying filament in the oven before printing is suggested. Constructed with Lexan, a readily available material at Home Depot and Lowe's throughout the United States, other plastics may work but Lexan yields the cleanest cuts with a circular saw - using a plastic cutter is strongly discouraged, securing clamps tightly to prevent kickback while cutting and wearing goggles are necessary precautions. A total of 18 inner and outer corners, plus 14 identical front and back cover brackets are required, each 3 inches deep to clear the traversing print bed and are designed for freestanding operation. Lexan clamps securely attach to the printer frame from beneath to secure the top, left and right covers in place. Before finalizing the position of these clamps, closely monitor the initial homing routine of the print head drive assembly to ensure a clear path; particular attention is needed at the back left corner of the top cover as obstructions may arise. All brackets and clamps are securely fastened using #6 x 1/2 inch self-tapping screws. For the Lexan material, multiple components can be extracted from a single sheet measuring 28 x 30 x .093 inches; however, two smaller sheets were necessary for completion of this design. Refer to an accompanying image to understand how these sheets were cut. A related project found on http://www.thingiverse.com/thing:1654725 features the integration of a filament guide which minimizes the gap and associated draughts encountered with the print head. The design process involved creating all clamps and brackets within AutoDesk Inventor software.
