Chainsaw with working handcranked chain

thingiverse

This is a chainsaw designed with a working hand-cranked chain. It's modeled after a well-known brand of chain saws. Many parts require support structures. I fabricated all the parts in PLA, but you can use any material that suits your preferences. Infill percentage shouldn't affect any of the parts. The longest pieces are slightly over 200mm, so they should fit diagonally on most printers. Sorry for the inconvenience, but I still haven't figured out how to orient STL files here so they're correct for printing. You'll have to rotate most parts to print them. There are two versions of the chain: flat and clawed. The flat chain is easier to print and smoother on skin if you expect it to be attacked with it. This chainsaw requires 44 links. The chain comes in groups of six, so print eight sets of these and you'll have a few extra links. Here are the required hardware parts: * Qty 4 - M4 x 12 screws * Qty 6 - M3 x 10 screws * Qty 4 - M3 x 22 screws The following STL files are necessary for printing: * QTY 1 - Handle_Body_v1.STL (no support) * QTY 1 - ChainSaw_chain_carrier_v2.STL (yes, requires supports) * QTY 1 - Chain_Sprocket_v2.STL (yes, requires supports) * QTY 1 - Turning_handle_v1.STL (no support) * QTY 1 - Turning_handle_knob_v1.STL (no support) * QTY 1 - Left_Cover_v2.STL (yes, requires supports) * QTY 1 - Right_Cover.STL (yes, requires supports) * QTY 1 - Handle_screw_side_v3.STL (no support) * QTY 1 - Handle_thread_side_v2.STL (no support) * QTY 1 - Top_cover_v1.STL (yes, requires supports) * QTY 1 - chain_carrier_tensioner.STL (no support) * QTY 1 - Handle_front_v1.STL (yes, requires supports) You'll also need to print eight sets of either Chain_v2.STL or Chain_v3.STL.
