i3 Mega Solid Frame

thingiverse

This is my take on a substructure for the i3_Mega_S Basicly there are two reasons why someone would want a base like this under their printer. One is to be able to install 60mm, 80mm or even 120mm fans to replace the crappy stock ones with. And the other being so one can relocate the SD-cardreader so you don't have to squeeze your hand between the spool and your printer anymore. This project is ready to be tested. Meaning, that I am printing it right now myself, confident that I will only have to make some minor "quality of life" adjustment in the future, but the design process is pretty much done. Print orientation: Keep the parts orientation the way it is right now. Blind holes, alcoves etc are designed to be printed they way the parts are oriented right now. Also, the parts will turnout way stronger if you print them as delivered, rather then flippen them around. <h3>Design steps so far:</h3> - Big "in takes" for big fans. Upgrading the stock fans with 60/80mm fans isn't doing anything for you, when you are suffocating them, by installing them in a frame whichs entire surface sits on the table/shelf/whatever you are placing your printer on. The intakes also make for greate "handles" to carry the printer by and keep you from having to use the metal frame around the Z axis to pick the printer up. - Optimized for 3D printing. Meaning, all parts have small tolerances (0.4mm) between them, to reduce the post-treatment, in case you printer is not 100% accurate. This is also represented by the alcoves for the M3 screws, allowing for an easy assembly. I am especially proud of the fact, that the upside down blind holes don't need any support material, since I found a way to design them soevery printer should be able to master them. - No fancy "dampers" Squashballs, selfprinted X-shaped dampers, etc. have the habit of making your printer "shake around" when printing. Sure, they do reduce the vibrations transfered to the surface your printer stands on and therefor they reduce the printers noise. But regular "felt funiture feet" do the same and don't throw your printer around. So this frames corners are designed flat and square on purpose, to allow you to install any kind and shape of felt stickers you can wish for. <h3>Things to work on</h3> - Documentation
