Making some t-nuts.
With the milling machine you make a T-bar into the right shape. To get the finished T-nut you only have to bore a hole in the middle of the T-nut and tap it with the right thread. So you get a useful product to clamp on things to the bed of the boring or milling crosstable.
Making a new carriage for my 3D printer.
The old carriage has some brass bushings and I replaced it with a new carriage that is able to house 8mm linear bearings. So I have reduced the play in the carriage. The brass bushings have certainly more play in the movement of the carriage.
There is something wrong in the cassette player.
Yes, I found it. It is fluffly, not a "grey" mouse and it rotates. Just getting it with a pair of pincers. And "voila", cleaning a bit and assembling it again.
Well there is no fun anymore to repair a MP3 player. The old stuff that were the days. But don't loose any screws, springs or small parts then you might get crazy. After that it worked just fine again.
Anti backlash solution in the Z-axis of my 3D printer.
Making some thread in a nut with FREECAD isn't easy. But with the helix function it is possible to make any thread you like. Because my lead screw is trapezoidal it took some multiple try-out samples to fit it. Finally it worked. With a 3D printer you can make any part you like to design. It is up to your imagination and drawing skills. Are you interested in designing in 3D: http://www.freecadweb.org/ .
Upgrading my 3d printer with a heating bed.
Warping or bending is one of the problems that comes with a 3D printer, when there is no heating bed installed on the printer. The plastic bends during printing, because of the colder temperature of the bed. The solution is an aluminium heating plate that I built myself. The groove I am milling is for the NTC-resistor that senses the temperature. PLA needs 70 and ABS 110 degrees Celsius. Well it is amazing, but it is as flat can be my printed part. I am very content with result.
