MAIN PURPOSE: Paint straight edges without masking tape
Hold the 220 mm straight edge against a ceiling line, skirting or window frame and paint right up to it: the shield keeps the brush off the next surface, faster than taping, and its handle keeps your knuckles out of the paint. Wipe the edge clean as you move along.

Print in PETG. Prints flat as a plate, no supports.
MAIN PURPOSE: Spray parts all round without touching them
Parts sit on eight thin ribs instead of a flat floor, so overspray never glues them down and their undersides stay clean; the base spins on BBs, so you turn the part while spraying instead of walking round it.

MAIN PURPOSE: Feed SMD parts from cut tape during assembly
Lay short strips of 8 mm component tape in the nine lanes and peel the cover back: resistors and capacitors stay in their pockets, in order and labelled, while tweezers reach over the low front wall. Hand assembly of a board goes lane by lane without spilling a single 0805.

MAIN PURPOSE: Measure and set servo angles
Lay the disc on the servo with the output shaft through the centre and fit the horn on top: the horn points to the engraved angles from 0 to 180 degrees, so you can centre a servo, check its real travel and set end stops before building it into a robot arm.

MAIN PURPOSE: Straighten DIP chip legs to row spacing
New DIP chips arrive with their legs splayed. Press one legs down into the 0.3 inch channel, or a wide chip into the 0.6 inch channel beside it, and rock it once: both rows bend to the exact row spacing and drop straight into a socket or breadboard.

MAIN PURPOSE: Cut copper tracks on stripboard
Push a 6 mm drill bit shank first into the socket and the handle turns it into a track cutter: set the point in a stripboard hole and twist, and the copper track is cut cleanly through without a drill or a craft knife lifting the copper.

A drop of glue holds the bit for good. Prints as shown on its floor, no supports. Stacked parts are fused into one print.
MAIN PURPOSE: Count wheel turns on a small robot
Press it onto the double-flat shaft of a yellow TT gear motor and let the teeth run through a slotted optical sensor: each tooth is one pulse, so a small robot can count wheel turns, drive set distances and keep two wheels at the same speed.

MAIN PURPOSE: Fold ribbon cable into clean right-angle turns
Lay a 40-way ribbon cable in the tray and fold it back over one of the 45 degree end walls: the crease comes out at exactly 45 degrees, so the cable turns a clean right angle inside a case instead of twisting or bunching against the lid.

MAIN PURPOSE: Space 18650 cells for building a battery pack
Holds eight 18650 cells upright at a 20 mm pitch with a 1 mm web between them, so a battery pack can be laid out, spot-welded and wrapped with every cell parallel and an air gap for cooling. Print two, one for each end of the pack.

MAIN PURPOSE: Seal a respirator away from dust and fumes
Organic vapour cartridges keep soaking up fumes and dust whenever they sit in open air. Seal the half mask and its cartridges in this snug box between jobs and they last many times longer, and the face seal stays clean and undistorted.
