Portable Coat and Purse Hook

thingiverse

This portable coat and purse hook follows the basic C-clamp mechanism to safely secure your purse and coat to any table up to 1.75in thick. Its small design (about 5in tall and 3.5in wide) means you can store it easily and take it with you wherever you go. The clamping mechanism makes sure the hook is secure to the table and can’t be accidentally knocked off or easily stolen. Some more difficult assembly is required. Instructions I’ve uploaded the Rhino, STL, and Gcode files along with a couple of pictures to help explain the process. You will need: -Safety glasses -Jewler’s saw frame and blade -Proper ventilation -Epoxy -Drill press/flex-shaft/hand drill -#22 drill bit -Soldering iron 3 M4 nuts, .70 pitch -1 M4x45 bolt, .70 pitch, fully threaded. At least 2in. head not important 1.) Download the file. Here are the print settings I used: 2.) Print the pieces. You will want to print the hook separately from the end caps, or else you won’t get proper adhesion in the end caps and they will lift during printing. (See pic) 3.) Allow print to set before removing carefully from bed. 4.) Before the print completely cools, break the supports that were created. I used the tip of a large half-round file, but anything strong and thin enough should work. (See pic) 5.) Drill the bolt hole with a #22 bit. (See pic) 6.) Cut off head of bolt. Try to keep the cut square to maintain the integrity of the threads. 7.) Check that nut threads onto the cut side. If nut won’t thread, put nut on other side of bolt and revolve until the nut is sitting at the end of the cut side. 8.) Place a nut in each of the voids and push in as far as possible. For the voids on the top cap and hook, this may not be possible yet.(See pic) 9.) In a properly ventilated area, use hot soldering iron to heat-set nuts into place. Try to keep nuts as level as possible. If void is too small, use the iron to carefully widen the hole until the nut barely fits. If nut comes loose, carefully melt plastic around the nut with the iron to encapsulate the nut. (See pic) 10.) Let pieces cool. 11.) Thread the bolt into both end caps and through hook. Make sure the flat disc end cap is on the inside of the hook. 12.) Carefully epoxy the bolt to the end cap nuts and let set. Any epoxy that bonds to metal should be fine. (See pic) 13.) Once everything is properly set, your hook should be ready to use. Please feel free to improve my designs! Also feel free to file and sand the hook to achieve a smooth look.
