Đế giữ PCB dành cho Zip Tiles

I have been using Heart Labs' great Zip Tiles to organize my electronic circuit prototyping and breadboarding. Because I don't have Fusion and was therefore was unable to easily use Heat Lab's parametric version of their holder, I created these PCB holders for common through-hole PCB sizes found on Amazon and elsewhere: 7cm x 9cm, 5cm x 7cm, 4cm x 6 cm, 3cm x 7cm and 2cm x 8cm, all 1.5mm thick.

Friction holds the PCBs in place in the holder.  Note that there are slight variations the nominal PCB sizes so sanding the edges of a board for best fit may be necessary. If your printer makes an elephant foot at the base of the holder it can be helpful because the foot narrows the PCB slot in a way that assists holding the PCB in place.

There's 3mm of space between the bottom of the PCB and surface of the holder to allow for solder joints and wiring etc. on the bottom of the board. Note also that care needs to be taken when removing the holders from a Zip Tile to avoid breaking a tile post. This is especially true of the 7cm x 9cm size that's held in place by two channels. I recommend using a small screwdriver to gently pry it away from the Zip Tile.

Because the footprint on the print bed is small, it's essential that the bed be very clean. Print time depends on the size and the speed of your printer. The holders I've made are PLA which works well for these models.
