If you print this and put it together, it may come out very weak. I sanded the tabs down a bit until they could fit if you applied pressure. Then I superglued them together, when its dried i take a bit of the filament. Put is in the gap, put parchment paper over it(make sure it stays in place) and iron it so it welds them together. Do this on both sides and its done!
Use zipties to fasten them onto the rails of the printer.(back rails)
The author remixed this model.
This model has a shorter base so it can fit at the right side of the eesythreed x1 without touching the parts of the printer. (WATCH OUT! THE TABS FOR THE CONNECTION PRINT WITH THE BOTTOM.)
