A new 3D printable model of an entomological pinning block

Intended for widespread use by entomologists, the block is applicable to large entomological collections with individual specimen numbering.

The proposed model of an entomological block is ready for printing on a standard 3D printer. In addition to the usual positioning of glue boards and labels along the Z-axis, the model also offers targeting devices that enable precise positioning of the entomological pin along the X- and Y-axes.

The model is offered in two variants – one for immediate use after printing and another that requires the fabrication of an additional steel rail measuring 100 × 30 × 5 mm, against which the tip of the pin rests during positioning along the Z-axis. The rail is also used to increase the overall mass of the fixture. The overall dimensions of the device are 100 mm in length, 35 mm in width and 37 mm in height.

The proposed entomological block is intended for widespread use by entomologists, particularly those using insect glue boards. It is applicable to large entomological collections with individual specimen numbering and its use can ensure that entomological pins are positioned on the label so as not to disrupt the integrity of the number or barcode. It can also be modified to suit the needs of the user and can be sliced and printed directly on a 3D printer.
