Want to shock your friends with an unusual and striking fidget toy? High-end spinners are now available. There are 2 versions of this model: 1. With Bearing 2. One-Piece-Print / No Bearings Needed! You can paint the spinner using metallic paint or even print out metal if you have the opportunity. You also can print one piece out completely of plastic without needing a bearing. I've prepared 3 variations of bearing handles for you. 1. With Bearing All tolerances are exact and ball bearings must be press-fitted with a vise or equivalent device. If plastic cracks, increase STL model by 1-2 percent and print again. Standard 608ZZ Shielded 8x22x7 Miniature Ball Bearings used in this model. The center bearing can be switched for a 608ZZ/C Ceramic Ball Bearing for increased spin time. Print Settings Resolution: 0.15mm 2. One-Piece-Print / No Bearings Needed! The design features built-in bearings. With a well-sliced file printed on an accurate machine, the bearing should be free or require little effort to break loose straight off the build plate. Once the bearing is freed, add a small amount of lubricant to the moving bearing surfaces (refer images) and you're ready to give your 'Fidget Spinner' a good spin. It may not be as good as a spinner with metal bearings, but they should still spin very well and are definitely fun to fidget with! TIP: Once the bearing is freed, apply a good spray of silicon spray or other light lubricant into the grooves between the main body and bearing on both sides of the spinner. Silicone is an amazing lubricant that makes 3D printed surfaces move really well against each other. WARNING: To achieve great results printing this design, you need a good slicing app and accurate machine due to the fine clearances applied. Although the clearances used should work with most slicing apps and machines, others may find it challenging and fuse the parts together. Fused parts can usually be freed; however, scaling up the design uniformly by 5 percent will increase internal clearances. This is an easy print of a fun gadget but requires an accurate machine to achieve necessary clearance between moving parts so it will spin well and freely. Applying lubricant is essential for getting a really good spin and being able to spin it with just one hand (Metal bearings also require lubrication). Print Settings Resolution: 0.15mm Limited offer!
