Not the most glamourous part but it is very functional, fast to print, roomy and blindfolded to place and remove. The total depth is 90 mm, which is the length of the stock spoolholder at the back. No screws, glue or magnets are needed. The holder simply hooks into the bottom-plate of the printer

The Bucket-Holder:

The first series of the X1 came with a lower ground-clearance / lower feet (ca 3 mm)then the later models, For the old model you have to take the V1 version of the Bucket-holder

Later models of the X1 and P1 have more ground-clearance (ca. 7mm) . The V2-version is for those newer model (see picture).

The holder hooks in the plastic frame at the bottom of the printer (it doesn't interfere with the feet). When placed you can slide around your printer as you like, as long as you don't lift it. It is very light, so no stress on the printer when sliding around.

Placing it is simple, tilt the back of the printer a cm, align the right extended edge of the holder with the backplate of the printer, and put the printer down. See photo's. When placed correctly you can rattle it left to right easily, meaning the printer is not resting at it and the printer's feet are down as it should.

The Bucket itself:

The bucket has a generous volume of over 1.5 liters. The original model is meant to print in spiral or vase mode. Because of that it is fast to print and very light and flexible so it won't rattle. Printed in regular PLA (0.4 mm) it is more than strong enough for its duty. Be careful when removing it from the buildplate. That is, like every vase, the most likely time to damage it (tearing off the bottom when it sticks to much). After that you can throw it around :).

A second bucket is added. Not a vase (1 wall), but with 2 walls/0.8 mm and flat sides. Looks a little neater and is a little stronger. On the bambu it costs surprisingly not too much extra time. Probably because of the simpler form.

Of course you can design your own bucket, the base is 120x80 mm (122x80.5 no tolerance), with 8mm radius for the two corners).

Happy purging :)
