FLSUN Corner Bracket

thingiverse

This is a heavily modified remix of the 2020 Corner Bracket by TheStapler. The design of the FLSUN Cube makes it impossible to build a totally rigid frame. Even tightening the corner bracket screws as much as possible doesn't solve the rigidity problem. Therefore, some kind of frame reinforcement for the corners is needed. I've created four versions: A - A reworked full-featured three-way corner bracket B - A shielded version of A C - A "drop in" version of A (no disassembly required) D - A "drop in" version of B (no disassembly required) All versions feature: Compatible with M4*10 hex head bolts Four bolts per bracket face (original has three) Cable routing channel recess built in The cable routing channel is for those installations that reticulate the control cabling within the unused channels of the aluminum extrusion. This makes it possible to still fit brackets to corners which have cabling reticulated through them. Obviously, bolts and t-nuts can only be fitted into unused extrusion channels. Pair drop-in t-nuts (or square nuts as supplied at default) with the C and D versions to avoid disassembling the frame. Note that the resulting structure may be less rigid compared to using the A and B versions. The shielded variants are designed to include the end caps for the Y-axis drive rods. These caps stop the rods from slipping out of position. A Cube will require two sets of two opposing corners for the top corners. Note: Fully equipping all eight corners will consume 96 x bolts and 96 x T-nuts (12 per bracket).
