With Inserts, you can mount a board in a box. For example, Arduinos, Raspberry Pis, ESPs, and protoboards.
The mounting holes of the inserts are always one outside the circuit board because sometimes component pins may protrude. If there’s a metal screw underneath, you’re immediately in trouble (short circuit).
The inserts are just extended to the outer dimensions of the board, which may mean there is no room for the connectors. Choose a larger box if you want to connect a USB plug to an Arduino.

3×2 Development board 60mm x 60mm.
A 3×2 Insert for a development board. The hole distance is 52 mm x 52 mm.
Download the STL file: Insert 3×2 PCB 52×52.stl


3×2 Breadboard
A 3×2 Insert for a protoboard. Use double-sided tape to mount the board on the Insert. This will probably already be on the back of the breadboard when buying.
Download the STL file: Insert-3×2-Breadboard.stl


3×2 Relay 30 Amp.
A 3×2 Insert for a 30 Amp Relay. This insert is a 3-part print because there are only mounting holes on 1 side.

3×3 Motor Driver TB6600
A 3×3 Insert for a TB6600 (Qwork WB10965) motor driver. Use an M4 nut and bolt to mount the driver. The front of the driver is slightly tapered, so when mounting the driver with the text at the top, the driver is slightly higher at the terminal side.

4×2 Motor Driver MD04
Insert for the MD04 Motor driver.
Download the STL file: Insert 4×2 MD04.stl



5×2 Breadboard
Insert for a breadboard. The breadboard is mounted with double-sided tape. This will probably already be on the back of the breadboard when buying.

4×2 Relay Board 8
Insert for a relay board with eight relays.
Download the STL file: Insert 4×2 Relay board 8.stl



5×3 Double Breadboard
Insert for 2 breadboards connected together. The breadboard is mounted with double-sided tape. This will probably already be on the back of the breadboard when buying.
In the example below, 1 power bar is moved from the middle to the side. This way, it makes it possible to mount an ESP VROOM board on the breadboard.
