Alfawise U30 - Tool rack for the left side

thingiverse

I didn't find any reasonable tool racks for Alfawise U30 here yet, so I made one of my own. This is my first self modelled design, so beware, there's a couple of flaws: DON'T USE A RAFT, BRIM, or SKIRT! The fitting to the aluminium extrusion is VERY TIGHT. I calibrated the desing with a 10mm bit of the profile but here the profile is 60mm long. I got it in place by forcing it through a bit of aluminium extrusion a couple of times. Any kind of raft, brim or skirt is going to make this very hard if not impossible. The leg of the machine is good for the job, but be sure you don't use a hammer on the side where the threads are, so you get your machine back together! The upside of this tight fit is that the result has a firm grip, so the rack won't move or vibrate during any print. I could have altered the profile by .1mm in every direction but with my present CADding skillz that would take me all day so I leave it be and just be happy with the tight fit. The hole for the wrench is a bit tight too. If you want it to be loose and free, make the hole .5mm wider. I thought that the wrench is so seldom used that it doesn't matter if it's a bit tight. You just have to put it in place really carefully and with two hands to keep the rack in one piece. And like this, it sits tight without vibrating and making any sound during printing. The holes for the allen keys are a bit wide. It seems that you can take .5mm of the radius of every hole but I haven't tested this. The rack mounts on top of the left side horizontal 20x40 extrusion behind the screen (if you have the screen on the left side). There are places for tweezers, wrench, allen keys, two screwdrivers, wire cutters, two micro-SD's and a 50mm scraper (60mm hole). It can be used with the screen cable clips (https://www.thingiverse.com/thing:3437162) and there's a little additional protection for the cable also. Feedback much appreciated !!!
