3D printed parts for Laser enclosure

I own a Sculpfun S9 laser engraver with a few enhancements (improved x-axis, air assist...). For safety reasons and because I didn't always want to wear laser safety goggles, I developed an enclosure. The enclosure itself is made of plywood - many of the additional parts are 3D printed.  

Cable drag chain

To guide the cables and subsequently also the air hose, I attached two cable drag chains, which are attached to the laser engraver using 3D printed parts.

Air support hose

When laying the air support hose, it was important to me to avoid sharp bending radii so that the hose is not kinked. The hose guide (hose_guide.stl) is attached to the  cable drag chain y02 (see picture above).

The 2-part gland (gland_A.stl and gland_B.stl) is intended for feeding the hose and the control cable for the compressor through the housing wall.

I designed a clamp to securely attach the hose to the tube of the Air Assist. An M3 screw and a threaded insert are required for the clamp. 

Lid fixation

The lid is attached using hinges and a mechanism that ensures an opening angle of just over 90°. This means that the lid remains open independently.

Suction

I chose a Noctua NF-A14  fan for the suction system. 8 M3 threaded inserts are pressed into the Suction_01.stl part. The fan protection grille (fan_grille.stl) is then screwed onto this part through the housing wall and the fan. The filter is then mounted on the other side. Brackets are available for two different fan sizes (Suction_02.stl and Suction_02b.stl). 

Fixing the materials to the honeycomb panel

Because the plywood panels I use for lasering are often a little curved, I thought about how I could best fix them to the honeycomb panel. It was important to me not to obstruct the travel path of the laser head and to minimize the waste of material through clamping etc. as much as possible. 

Laserfixture_A is used to fix the workpieces to the honeycomb panel. In order to be able to print the hold-down devices (the small notch that hooks onto the edge of the plywood panel is important), I designed the component in 2 parts. The strips are glued to the panel. The balast containers (Ballast_container_50x50x100_A.stl and Ballast_container_50x50x100_B.stl) are simple hollow blocks that I filled with sand and then closed with epoxy glue.
 

Laserfixture_B is used on the edge of the honeycomb panel. There are 2 M3 threaded inserts in the Laserfixture_B_01.stl part. There are different Laserfixture_B_02 plates (for 2mm, 3mm and 4mm) to be able to clamp plywood panels of different thicknesses. The small notch is also important here. Laserfixture_B is partially pushed under the honeycomb panel, this raises it slightly and the plywood panel is clamped directly onto the honeycomb panel. For this reason, several Laserfixture_B_01 must be distributed around the honeycomb panel so that it lies straight. In the non-clamping area, the Laserfixture_B_01.stl can be cut in height in the slicer to save material.
