Swiss Army Knife Style Key Holder Design last updated February 23rd, 2018 All necessary information is included in this description. If you have further questions, please ask them in the comments section. This design is free. If it becomes a daily use item (like for most people), consider showing your appreciation with a tip. My profile page has details on how to do that. You can also use PayPal; just contact me for the address. Creating these designs and refining them based on feedback takes time and effort, every contribution helps! This key holder functions like a Swiss Army knife, folding keys into place. Each holder is designed with an equal number of keys at each end. The center bolt keeps keys from crossing over onto each other. You can fit as many keys as you want on this design; just get a long enough bolt. NEW Old-fashioned key size: This edition has been requested and sized to fit a general-purpose old-fashioned key (see image). You will need spacers for this one - check the files. This size is larger than the standard key size, with a length of 112mm and a width of 33mm. Choices: 3mm Bolts 2mm Bolts Large Key Ring Small Key Ring Materials Needed: PETG, HTPLA, or ABS are preferred materials. Anything stronger will also work. PLA may be too weak for regular use. 3x bolts 3x nuts or knurls (If you don't know what a knurl is, then look at the pictures. You can buy them in packages online. Check the image for knurl dimensions needed) Bolt Sizes: Both 3mm and 2mm bolts can be found by measuring the thickness of the keys you want to put into the key holder + 6mm. example: 6 keys with 3 at each end (pictures). 3 keys total width is 10mm + 6mm for keyholder body insets = 16mm bolt length. Knurl Sizes: There is a picture with the suggested dimensions of the Knurls. 3mm and 2mm knurls have varying dimensions based on manufacturer. They won't work unless you have the proper dimensions to grip the holes. Knurls can be easily put in with a large set of pliers/clamp/hammer. They need to be pushed into place so that the edges cut and grip the hole. Key Spacers: There are two sizes of spacers. You can use a washer if you want, but plastic spacers may be better for the keys. Standard Key Spacers come in 1mm and 1.5mm thickness Old Fashioned Style Key Spacers come in 1mm and 2mm thickness. You can make your own easily through www.tinkercad.com if you don't have a CAD program. Note: I personally don't use spacers since I like how the keys grip each other and stay together in my pocket. It's all personal preference. Printing: Print with the inside face of each part on the print bed. This should work perfectly for any printer. Try using high infill - 75% or above when printing. Any ideas let me know. Enjoy!
