These are "Mean Well" type power supply mounting brackets. You will be able to mount this type of power supply on a surface using screws. This bracket is quite sturdy. The slot on the bracket that holds the power supply supports up to M4 screws. It is recommended that you use washers. The hole used to screw the power supply to the surface are 5 mm in diameter.

This is a mounting plate for a Dual 16850 Battery Holder. It allows to screw the battery holder to a surface without having to put screws inside the battery holder. It prevents damages to the battery that could be made by using inner screws. The holes for the screws are 90 mm apart. The plate is 40 mm x 75 mm. The screw holes are 3.25 mm in diameter. The plate is 1 mm thick.

This is a simple holder for a FS-iA6B Radio Receiver. The holder is 49 mm wide, 12 mm in height and 10 mm deep. The mounting holes are 39 mm apart and uses M3 or #4 screws.

This is a X axis height adjustment tool designed for the CR-10, especially if the Z axis upgrade is installed. Nevertheless, it can be certainly used for other 3D printers. You need to print two tools to use it.

These are mounting plates for the mini and half size breadboards. Sometimes, I use a breadboard temporarily for a project. It is messy to remove it if it was sticked to a component of the project using the double sided tape underneath it. Also, it is difficult to re-use it. So, I have design these mounting plates. I stick the breadboard on a mounting plate and use the holes to mount it on the project. It is then easy to remove and re-use it in another project. The mounting holes are 48 mm apart for the mini breadboards and 67 mm for the half size breadboards.

This is a mounting plate for the classic Arduino's Duemilanove/Diecimila/NG/Uno and any other ones that has the same form factor. This mounting plate serves three purposes:

This is a mounting plate for the dual motors driver board that uses a L298D. They are widely available. This mounting plate serves three purposes:

This is a led strip holder that latches in the X axis extrusion slot of a CR-10 3D printer. You attach a led strip to the bottom to light up the bed while printing an object. This is a remix of http://www.thingiverse.com/thing:2252158. I removed the bottom grove. It can be now used with wider led strips and printing support is no longer required. Also, I increased its length to 24 cm and this version is wider: 22 mm. I have added two holes to hold the the wires with zip ties.

This is a privacy shield that you put on your Logitech C170 webcam in order to block the lens and thus to ensure your privacy.

This is a simple robust cable holder. Why robust? The other ones I designed were too weak. With time, they were bending from the weight of the cables. With 8 slots, its overall size is about 15 cm (W) x 4 cm (D) x 2.5 cm (H) or 6" (W) x 1"1/2 (D) x 1" (H).
