{"product_id":"light-duty-hammer-metal-3d-bolts-tpu-grips","title":"Light Duty Hammer (Metal\/3D Bolts, TPU Grips)","description":"\u003cp\u003eA printable hammer with TPU grips meant for light duty, not construction sites. I couldn't make a sturdy 3D printed nail puller, so that is omitted from this design. The hammer has a nice weight and is well balanced when the appropriate metal bolt is installed.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBolt Compatibility\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eI recommend 5\/8in (~15.6mm) bolts for the hammer face. The bolt can be screwed directly into the hammer.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eBolts that are smaller will work if they are around 3.5-4 inches (90mm) total length. Use a nut to secure it into the hammer head.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eA 3D printed bolt is also included in the files with a printed pin to secure it in place. I would only use this to print a soft hammer face out of TPU.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGrips\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThere are several grip styles to choose from, but none are required. To install the grip, press or hammer (ironic) the hammer into the grip. There is a horizontal line on the hammer shaft which shows where the top of the grip should reach.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy bother?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe cheapest 10oz hammer I found was $7.50 at the hardware store. So it was more expensive for me in time and effort to make this hammer. By a lot. BUT, now that it's made, anyone can print a hammer for…$3? I was tired of various hammers being lost around the house so it's nice to have a few cheap ones around. And they do look cooler than a generic wood handle hammer. Anyway, consider this as a case study, I suppose.\u003c\/p\u003e\u003cp\u003eDesign by secv808 on MakerWorld (license: BY-SA).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67415187915056,"sku":null,"price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_2e7e92d7-2a52-40c9-8f38-07abcba854d2.png?v=1785405632","url":"https:\/\/mymadmanlab.com\/products\/light-duty-hammer-metal-3d-bolts-tpu-grips","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
