Zero Offset E3D holder for Maker Select Mini

thingiverse

This is a zero offset E3D holder/mount for a Maker Select Mini (Maylan M200) printer. The part was first teased on the Maker Select Mini Facebook page and Hackaday over a month ago, but the STL file remained unavailable. Instead of waiting any longer, I created it in 123d Design. This design is included so that you can customize the mount for your E3D--mine is a clone and may be different from the original or other clones. The clamp part is reversible, allowing you to use it in whatever orientation works best for your wiring arrangement. Additionally, this holder does not include a fan mount. I currently use a fan/cooler holder like this: http://www.thingiverse.com/thing:839620 I am including a reference to the Hackaday article for background information. https://hackaday.io/project/14823-monoprice-select-mini-maximum-3d-printer-mods/log/46025-zero-offset-e3dv6-clone-hot-end-mount Required hardware: 4 x M3 nuts 2 x M3 x 20mm screws You can use the existing cap screws on the X carriage, but you will only get about 2 or 3 threads of engagement. This was an area of the design that I struggled with: making it too thin causes the nuts to pull through; making it too thick prevents the exiting screws from engaging the nuts. With this design file, you can make changes to suit your needs if you are not happy with my choice. About the pictures: The green part was rapidly printed in PLA to test fit and clearance. This is why the printing surface is of poor quality. The 5 test models took about an hour each to print. The white mount is in PETG, which is the finished, working part and took about 2 hours to print at 100% infill. Print Settings Printer: Wanhao/Monoprice Maker Select Rafts: No Supports: Yes Resolution: .2 Infill: 100% Notes: I printed mine in PETG. I recommend PETG or ABS only for this project. I also recommend supports. The two blind holes are a very close fit, and any sagging filament or loose strands will prevent the mount from firmly seating to the X carriage. How I Designed This 123D Design Change it to your hearts content. If you remix it, please reference it. I would love to see what changes other people make.
