Removable/twisting top part design for refillable 2 in 1 botlle

i need the casing design to house the conceptual mechanical mechanism, aim of the 3D printer Robust, aesthetic and functional, very easy to use, a must have for anyone who wants to experience 3D Printing; almost all parts are 3D printed;

I want to build a 3d printing machine out of 1/4” plywood and wooden dowels. To win the prize, I need a 3d rendering, a explosion picture of the system and a dxf or dwg file showing all the parts laid out for cutting by a cnc machine. The goal is to Repstrap a 3d printer similar to the Wally. The first thing to do is review the Wally blog at http://forums.reprap.org/read.php?185,220993 The next thing to review is the git hub site. https://github.com/NicholasSeward/ConceptFORGE/tree/master/Wally This has all the files for dimensions and parts needed This will be the starting point, nothing is set in stone, If you need things to be bigger or smaller, that is ok. 1. I have included a variety of pictures and ideas. Use them as you wish. 2. I see the arms built out of 3 layers of plywood. Bearing on top, bearing on bottom and the middle piece has a smaller diameter hole to keep bearings from falling through. Ply wood dowels should be used for indexing assembly. 3. Bearings are being used for both smooth motion and rigidity. 4. The frame and table should be tabbed so that the parts push together and self align. 5. The back is to be 2 layers. For a total of 1/2”. The back should be inset a 1/4” to allow for a future modification. 6. All parts that can ( brackets) should be tabbed to self align and position. 7. I would like to be able to flip one of the arms and have it line up with the other arm. This is for a future change to add a central carrier. (like in the original design) 8. Shaft connections to motors need to be figured out 9. To tighten the fishing line, I will be using guitat pegs. There needs to be a hole for a dowel to lock in position. 10. I would like to get all the pieces on the front side of the printer. If dimensions need to be made to frame, that is fine. 11. Bed will be multiple layers. There should be a bottom, a ring to open center to 1/2” (for a heated bed) and a pice of glass will sit on top of this. 12. Pulley to arm attachment. I have a couple of ides on this. One is to use a dowel into a bearing another is to tighten the bolt and then have a plywood key that fits around outside of bolt and keys into pulley or arm. 13. The bearings are cheap. If an extra bearing makes something easier, use it. 14. File will be cut using an 1/8th inch bit. Adjust slots for this. (ie. Add a 1/16th of an inch to each side I am sure there will be lots of questions. I will answer them as they come up. I will also send a kit (plywood and bearings) to the winner.

I am looking for a model of a pistol grip. Mostly angular, but smoothed over, does not need to be ergonomic. I have supplied a drawing of the mounting surface, it must be compatible with this, in that file there is a sample grip outline size reference, grip designs must be close in size to what is supplied, grip width is 1.2in at the maximum. Grip angle must be 13.5 degrees less vertical than 90 degrees. A non textured, non photo realistic model. Must be symmetrical.

Hello, I have a Iphone 5 case design. I need it done in cad in order to get a quote on manufacturing the prototype, the case has four layers three of which have two parts. I need to get started on this ASAP. Thank you

We want a smartband design for our new product. The smartband should look modern and rugged. Should be composed of an monocrhome OLED 0,96'' 3 leds with different colours and 3 buttons aligned with the leds The buttons and the leds should be placed on the top of the device and not on the side as many watches. We would like to follow the colours of this band as it gives the idea of safety and of been rugged: https://toughphones.net/product/mtt-smartwatch-protection-tough-smartwatch/ The size should be close to 47x31mm but can be a bit different.
