Quick description is:- The rear portion stays attached to the printer. The front portion is held in place by Eight 6x3 magnets. When you need access to the tool head, you simply pull the front portion off and that's that. Instant access.
I'd advise printing at 40 percent infill in ASA or PETG at a minimum. I settled on using 3 walls as that allows more flexibility when fitting the stock vent block to the print.
For anyone wondering why the rear is not just included in this file set?I have an idea for a modified frame for adding an extra option. Getting around to actually finding the time to do the mod is a whole other subject. But when (if) it gets done, I don't want to have to edit every version when I can just add it to that one file set.
The author remixed this model.
Added angry faces, changed opening for the fan, slightly tweaked shape along edges, changed hole depth and added easy print holes for top.
