Prusa Mini Top Mount Spool Holder

thingiverse

Nice top mounted spool holder for the mini/mini+. I created this because of a lack of spool holders for the mini. I posted my original design on the Prusa groups and almost instantly faced backlash about how dumb it was, and that it would mess with my z axis and create to much sag etc... Even though I was belittled, I decided to build it and test it out.. what did I have to lose? If it works great, Ill have a nice compact top mounted holder (similar to the Kingroon KP3s style) I decided to test their theories and found no immediate issues to be honest. I tried printing at the max usable areas on both x and y axis.. I used an entire roll of PETG testing this.. and I'm more than happy with its design and overall results. This particular build will require shallow "m4x 0.7mm" heat inserts to be used in order to attach the MODIFIED OEM SPOOL HOLDER. (3M adhesive tape can be substituted however). First to print is the spool holder feet. These will replace the oem spool holder feet with a set that can be screwed down OR 3m taped to the top platform that will be printed next. Print these laying on their side so you won't need supports. Print 2x of these. The platform itself is pretty simple to print. Print it upside down so the large flat surface is on you bed. it won't require any supports then. Lastly is the Bowden tube bend support. This isn't critical but it does help a lot. This little fella slides onto your extruder Bowden tube (or filament sensor) and gives it a nice swooping 90 degree bend over a 2" span. This helps point your tube upwards so that when your filament is being pulled from the TOP of the roll downwards, there's less chance of issues or snagging. This could easily be made or modified to go further or bend more. Your decision there. Ill try to add photos. No promises tho. they always seem to exceed maximum allowed size?
