Mini desk top drill press for drilling PCBs and 3D printed plastic.
If you cannot find the same motor which i have used then designing your own clamp shouldn't be too difficult. This could be a good idea anyway since my motor is not very powerful at all.
Parts which are not 3D printed:
M4 Threaded rod, (2x 190mm length),
Aluminium tube (I.D. 4mm) (O.D. 6mm),
Linear Bearings (2x need to fit onto the 6mm rod),
11mm Cir-clips for the bearings,
Motor (salvaged from old electronics),
Chuck available here: https://www.aliexpress.com/item/F85-1-set-7Pcs-0-5-3mm-Electric-Drill-Bit-Collet-Micro-Twist-Drill-Chuck-Set/32601527405.html
I printed it on a low resolution, cheap printer, but it is designed without any small features so high resolution is not necessary.
the parts are likely to need finishing after printing. My printer is a cheap one so all of my parts had to be perfected with a file and modelling knife.
The rack and pinion obviously need to mesh together smoothly. And the aluminium tube needs to be a tight fit within the base and header to avoid vibrations.
I needed a small drill to make holes in PCBs and to tidy up holes in 3D printed parts.
Whilst looking around online, i found a micro drill chuck. I had a motor laying around which had the correct shaft size, so i designed the rest of the drill press around the motor.
It has been designed to be simple, without the need for a high resolution printer for fine detail.
