Chunky - the one for all tent peg | multifuntional, DIY, for hard grounds

Description

This is Chunky ============= the multifunctional tent peg ----------------------------------- Of course it is only a peg if you add the metal wire nail. It is designed to work with cheap but big nails with a diameter of 6-7.8mm. Bought pegs are weak, expensive or don't fit my needs. Originally I designed different models for different use cases but then I combined them all into this "Chunky" model. All the features of Chunky: ===================== * closed tube part for cords up to Ø5mm * multiple holes for different use cases (cords, hooks, springs) * big open hook / rail for quick setups and release | V2: Sturdy open hook * 30 x 3 mm slot for flat straps / belts * turn the Chunky upside down and use it as a "washer" or retaining disk for ropes of any size or small closed tent loops (you may fiddle them through a hole or the slot) * nail head fits in the "sink" so you won't hurt your feet * use bright colors for better visibility, don't step on them or leave your Chunkies behind! * user defined stability with your print settings: Do you want the peg to break or your tent? * can be printed flat or upright for different layer orientation, only safe overhangs and bridges in both orientations, no support needed * temporary setup with wire nails, permanent setup with screws possible * good look and feel! Chunky! What you need: ============= I use it with Ø7,6mm x 260mm DIN 1151 nails . Nails and 3D printed parts are cheap and easy to replace. 7.6mm fits best. Any nail with Ø6-7.8mm (8mm model) and a length of at least 15-20cm should work. I'll add a 6mm model for smaller nails but they may be to short or don't stick in the ground. Transform any of the models in X/Y or X/Y/Z direction with your slicer for your needs. Usage Information: =============== Too much vertical (90° angle upwards) force on the Chunky may break it or small parts of it, especially on the rail / hook side. So don't just pull your cords to remove the peg from hard soil but rather try to carefully lever it from underneath. Try to apply forces more horizontally. Of course the Chunky can break if you miss the nail and hit it with the hammer. The Chunky is very robust but the tubular part will most likely break. Do some test prints and try to break your Chunky at home - you will learn a lot about your filemant and your print settings and tune them to your needs to avoid a bunch of broken Chunkies when you are far away from your printer! Miscellaneous: ============ This is a work in progress. I will update the design after some tests in the wild. I also added the monofunctional predecessors (I uploaded them as a remix) but I don't want to think about them if I just can grab a handfull of Chunkies. I will start with V1 and keep the old versions online if they aren't a total desaster, but please always use the newest version. With my settings it's 6-8 grams of filament per Chunky so about 0.15-0.3 € / $. The steel nail is about 0.1-0.3€ per piece. It gets expensive if you use stainless steel, but I don't mind some dirt and rust on the nail. It won't fail anytime soon, can be brushed easyly or even cleans itself in the soil. Maybe I can design some kind of rippled skirt around the nail for soft soils or sands. Thank you for reading! I had a lot of fun with this project and I'm sure I will use and maybe update the Chunkies for the rest of my life and it was worth the work just for my own use! Existing tent peg models on thingiverse are nice but did not fit my need. I think mouserunner's https://www.thingiverse.com/thing:342506 is a clever design for light tents and small loops but I needed more! I don't even have a tent but I will use a flat strap and the Chunky peg to support the awning of my camper, where it will be held in place by "Hooky" the funny snake hook - see my other prints! Feel free to comment or remix the design but don't violate the license. I take so much from the community for free (knowledge, tips, designs) and this is my part of giving something back. Of course you can print it for your friends and family and have them cover your expenses! Tips for printing: ============= You need to find a good filament with good layer adhesion and find you own settings. You should use 4-5 perimeters and at least 5 top layers (in case you miss the nail and hit the model). Infill is not important, I use 10% gyroid but I added a local modifier to have 100% infill or 15 top layers on the "hook" side (opposite the tube), which is the weakest point. You can use weaker settings, if you want the peg to break instead of your tent. Or you don't think about it at all and use 100% infill, which is still cheap and only uses 10-30% more material at 4-5 perimiter setting. A model of this size will never be expensive, don't think to much about that. This is a functional print that you are going to hammer in the dirt, use 0.2 or 0.25mm layer height for faster print times, we don't need any beauty here. If you still have problems with layer adhesion, you might want to print it on its upright on its side. I use PETG, which has good layer adhesion and it should not break in case I miss the nail while hammering - update: it breaks. Try it, use version 2 or better material like PCTG, ASA. Some hard TPU (A95 and harder) might also be a great idea and is worth a test. Use UV resistant filament for permanent setups. Update late 2021 & Version 2 ======================= I use the Chuky many weeks a year while traveling. It works really well on hard ground, none of them broke on a functional usage, some of them broke because I missed the nail or while removing the nail from really rocky hard ground. I will only use ASA or TPU Chunkys, once my PETG Chunkys are gone. Maybe the new PCTG is a better option due to better impact strenth. I updoaded Version 2 which has a better open hook. The version 1 open hook rail was flimsy (not chunky) and broke on the thin layer lines.
