Pegboard Rivet with filament

prusaprinters

<p>In my search for the perfect 3D-printed rivet to use with pegboard holders on my current pegboard, I developed the CrabRivet. The rivet here is intended to be used on 1/4 inch thick pegboard with 1" hole spacing and 1/4 inch diameter holes; which I find common in North America. Since a rivet needs to be closely coupled to the specifications of the actual pegboard, you will need to measure your pegboard to see if it matches.</p><p>In printing and using many of the existing holders that use the older "hooks", I found tools were not held snug. I printed existing PLA rivets with varying success. In using a plastic rivet, an insert causes the 'feet' to expand resulting in a tight fit. Using a piece of filament is the most convenient insert for makers which also gives strength to the rivet and allows it to be printed face down, which yields a better looking result.</p><p>I've attempted to solve the filament hole problem by using a tapered hole which will expand the ends of the rivet for a tight fit. The rivet is a flat head, designed for holes that are 7mm in Dia. It is designed to be flush mounted with a 11mm hole. It requires 2mm of plate material. See Drawing.</p><p>Part of the problem in making rivets is that printer/slicer settings differ and FDM has difficulty in making precise small holes and so you will need to test the rivet to see if it works for you. I can change the tolerances to make other variations if there is a need.</p><p>You may need to clean the rivet of any excess plastic and I find a 1/16 or 2mm drill bit helpful to ream out the front hole. I printed mine in PLA at 0.2mm. No support or brim was needed in my tests.</p><p>I've included 2 test holders you can try. The pliers holder may need some support. I went to Printer Settings &gt; Support Material &gt; Overhang threshold and set to 10.</p><p>If you need to remove the rivet, first push the filament through with a small hex key or driver.</p><p>If you try the rivet, let me know if it worked as I might be able to modify for your needs.</p>
