Anet A8 Shelf Frame Support

thingiverse

My 3D printer is sitting on a shelf with another shelf right above it, anyone with an A8 knows that the lack of rigidity is a major issue that seriously reduces print quality... There are plenty of large frame braces available, but why go to that extent when you have a shelf above that can be used as support... Print 4 x Rod supports, use these along with 8 x M3x30mm, 8 x M3 washers and 8 x M3 Nyloc nuts to get your printer bolted down solid and square on the shelf it's sitting on... Next, you need to print 2 x Top Support Brackets, 1 x Top Support Screw LH, 1 x Top Support Screw RH, 1 x Top Support Machine LH & 1 x Top Support Machine RH. Use a 3MM Drill Bit to drill holes in the top plate of your printer to attach the part 'Top Support Machine', then bolt through with 3 x M3x16mm screws and secure with washers and M3 nyloc nuts... Screw the 'Top Support Screws' into the 'Top Support Machine' Plates, and then place the 'Top Support Brackets' on top. Unscrew the 'Top Support Screws' until the 'Top Support Brackets' form a good contact with the bottom of the shelf above. Mark the screw holes through the 'Top Support Brackets' on the bottom of the upper shelf to mark its location, then screw in the 'Top Support Screws' again to give clearance to be able to affix the 'Top Support Brackets' to the underside of the upper shelf using self-tapping screws. Once the 'Top Support Brackets' are securely fastened in place, unscrew the 'Top Support Screws' so that pressure is applied between the screws and the 'Top Support Brackets', applying tension. Optional Spanner design included if you need to tighten in a tight area... Enjoy your newfound frame rigidity and increased print quality as a result!
