There were a number of parts that needed to be made\/printed, either because the kit did not actually contain any printed parts, or because I decided on changes\/upgrades to the base Hadron build.<\/p>\n

Some belt grips, one set for the X and one for the Y axis.<\/p>\n

\"\"<\/a><\/div>\n

Some brackets to attach the power supply to the underside of the Y axis – these are a design by<\/span>\u00a0<\/span>inventaholic<\/a>\u00a0available on<\/span>\u00a0<\/span>Thingiverse<\/a>.<\/span><\/p>\n

\"\"<\/a><\/div>\n

Brackets attached and the power supply centred on the Y axis profile.<\/p>\n

\"\"<\/a><\/div>\n

A pair of end caps, one for each of the Z axis profiles.<\/p>\n

\"\"<\/a><\/div>\n

Here is a closeup of one in place.<\/p>\n

\"\"<\/a><\/div>\n

I want to try using auto bed levelling on this printer, so I printed a couple of parts to use with a 9g servo that allow it to be attached to the underside of the extruder platform. The bracket is a design by\u00a0delavar<\/a>, the arm a design by\u00a0zennmaster<\/a>, both available from\u00a0Thingiverse<\/a><\/p>\n

\"\"<\/a><\/div>\n

Here they are attached to a servo, I am still awaiting my shipment of microswitches, so again this will have to wait.<\/p>\n

\"\"<\/a><\/div>\n

The extruder platform did not come powder coated, so that is another item on the to-do list.<\/p>\n

For the Z axis lead screw couplings, I thought I would try a design by\u00a0nophead<\/a>, also available on\u00a0Thingiverse<\/a>.<\/p>\n

\"\"<\/a><\/div>\n

It makes use of some plastic tubing over the end of the motor shaft for a tight fitting yet allows for some flex in the threaded rod whilst still ensuring a coaxial connection between the threaded rod and the motor shaft.<\/p>\n

\"\"<\/a><\/div>\n

I made a couple of lead screw nuts from a piece of acetal\/delrin, these will work in conjunction with the stabilising arms that came with the set of parts.<\/p>\n

\"\"<\/a><\/div>\n

If I install a spring between the lead screw nuts and the stabilising arms, I will in effect have an anti-backlash nut, since they are both threaded.<\/p>\n

The build calls for 4 x Misumi<\/a> HBLSD5<\/a> brackets, that Misumi<\/a> sells for 0.88 Euros each (plus P&P), or I can buy an equivalent on Ebay<\/a> for \u00a32.50 each, but I decided to buy a 1m length of 20x20x3mm aluminium equal angle for \u00a38.98 and make my own.<\/p>\n

\"\"<\/a><\/div>\n

They are 34mm long so the cost in raw material (including wastage) for all 4 was under \u00a31.35 for less than 150mm of material, and plenty left over for other projects.<\/p>\n
